Fiber Lasers as a tool for the treatment of kidney stones

Fiber Lasers as the treatment of kidney stone diseaseThe treatment of kidney stones is regarded as a painful process, however, specialists from the U.S. have developed a laser technology to make the therapy easier for patients in a way never done before. According to specialists, a two-month test makes the medical center the first in North America to apply pulsed fiber lasers to take away kidney stones.

The development of this laser technology takes a couple of years on project. That is why the specialists try to make Ohio State the first to employ it, as it already had some experience. To be more precise, specialists started developing the opportunity of applying this type of fiber laser system for urology in early 2015. By mid-2017, certain benefits of the new laser technology were over to the conventional state of the art.

The fiber laser leads to kidney stones’ breakage into tiny pieces. Herewith, such a laser system is considered to be more consistent compared with traditional laser technology. The operating principle is based on laser beam energy that breaks up the stones: “Once we get to the stone, the laser beam energy is delivered through an optical fiber that’s brought into contact with the stone. Once you’re touching the stone, activate the fiber laser system. And it delivers pulses of energy to the stone that breaks it up.”

The main benefit of such fiber laser treatment is a short time of breakage resulting in less required time under anesthetic and a faster recovery for patients. The thing is that the previous laser systems applied for kidney stone procedures are dated. They have been used for about 20 years and had numerous limitations. While modern pulsed fiber lasers are one of the biggest breakthroughs in urology. The developed fiber laser meets the scientist’s expectations. It allows breaking up really big stones that were difficult to treat with the older laser system.

Additionally, there is no often a need for stents because the new fiber laser system enables to efficiently break the stones into tiny parts and dust. It should be noted that a stent is a temporary tube between the kidney and the bladder that helps the kidney drain. Herewith, it provides discomfort to patients and requires an additional procedure of its removal.

Also, the pulsed fiber laser offers other advantages for medical staff, for instance, it is smaller and more portable than the previous model that required a special outlet in operating rooms. The main goal of fiber laser development is to help physicians get better clinical outcomes for patients. Thus, the laser system is planned to be used in areas of the hospital where traditionally haven’t been used before.

Fiber Optic Sensors find cancer biomarker

Fiber Optic Sensors detect cancer biomarkerA team of researchers from the Netherlands has developed chip-based fiber optic sensors with integrated laser systems to allow finding low levels of a cancer protein biomarker in a urine sample. Such fiber sensing technology is considered to offer more sensitivity than previous techniques, resulting in noninvasive, inexpensive fiber sensing ways to identify molecules that are responsible for the presence or progression of a disease.

To be more precise, such a fiber optic sensor enables researchers to make label-free detection of S100A4 that is regarded as a protein connected with human tumor development at clinically relevant levels. According to the team, fiber sensing technology promotes faster and more sensitive findings of tumor biomarkers, which favor faster treatment and better results.

The principle of fiber sensor operation is based on “the detection of specific molecules by illuminating the sample with an on-chip microdisk laser system, made with aluminum oxide”. Thus, it is possible to use aluminum oxide doped with ytterbium ions to manufacture a fiber laser that emits in a wavelength outside the laser beam light absorption band of water, while still allowing the accurate finding of biomarkers. Herewith, the frequency or color of the laser beam changes in a detectable way when there is its interaction with the biomarker under consideration.

The laser pump light equipped with the fiber optic sensor performs lasing in a micron into the resonator. Herein, fiber probes are held on the resonator surface capturing the required analytes. Then the laser beam in the ring goes through the fluid, and the attachment of required analytes shows the frequency shifting of laser system emission. Finally, it is possible to accurately measure this shift allowing the detection of minute amounts of analytes flowing over the fiber sensor in a “specific” way.

Despite the fact that fiber optic sensors that monitor laser frequency shifts are not novel, they are often regarded as not easily installed on small, disposable photonic chips, while aluminum oxide can be easily manufactured monolithically on-chip, herewith, it is compatible with conventional electronic manufacture procedures. Such fiber lasers enlarge their opportunities due to unprecedented sensitivity because of much narrower laser beam linewidth than the resonances of passive ring resonators. When other noise sources are overcome, this fiber sensing will enable the finding of minute frequency shifts from biomarkers at very low concentrations.

The developed fiber optic sensor has been already tested in complex liquids such as urine resulting in the detection of S100A4 at concentrations as low as 300 picomolar. Nowadays it is planned to integrate all the relevant optical sources and signal generation components onto the chip to make the fiber sensor even simpler to operate.

Fiber Optic Sensors favors better in photoacoustic microscopy

Fiber Optic Sensors in photoacoustic microscopyA Chinese team of researchers has created a new twist on fiber optic sensors. It promotes the development of a smart flexible photoacoustic imaging technique, which is regarded as a way to enlarge new applications in portable devices, instrumentation, and medical diagnostics.

The operation of the new ultrasound sensor is based on fiber lasers that rely on fiber optic technology to manufacture fiber sensors for photoacoustic imaging. To be more precise, these fiber laser systems apply fiber optic ultrasound determination, utilizing the acoustic effects on laser beam pulses via the thermoelastic effect (temperature changes).

The thing is that traditional fiber optic sensors trace very weak signals due to their high sensitivity via phase measurement. Herewith, this type of fiber sensor can be employed for military purposes to find low-frequency (kilohertz) acoustic waves. Nevertheless, they provide weak operation for “ultrasound waves at the megahertz frequencies used for medical applications because ultrasound waves usually propagate as spherical waves and have a very limited interaction length with optical fibers”.

It should be noted that the main application of the novel fiber sensors is medical imaging, herein, they offer better sensitivity than the piezoelectric transducers in use today. Components of a special ultrasound fiber optic sensor include a portable fiber laser set in the 8-micron-diameter core of a single-mode optical fiber. The standard length of the fiber optic system is only 8 millimeters.

The team uses two highly reflective fiber Bragg grating mirrors written into the fiber core to achieve optical feedback to manufacture the fiber laser. Then they dope the optical fiber with ytterbium and erbium to result in efficient optical gain at 1,530 nanometers. Additionally, a 980-nanometer semiconductor laser operates as the pump laser.

The applications of such fiber laser systems with a kilohertz-order linewidth (the width of the optical spectrum) can include their use as fiber sensors, so they provide a high signal-to-noise ratio. Also, ultrasound detection takes advantage of the combined methods because side-incident ultrasound waves spoil the optical fiber, modulating the laser beam frequency.

The fiber optic sensors based on fiber lasers are highly promising for application in photoacoustic microscopy. The team applies a 532-nm nanosecond pulsed laser to illuminate a sample and excite ultrasound signals leading to a photoacoustic image of the vessels and capillaries. Moreover, it is possible to use the fiber optic system for structural imaging of other tissues and functional imaging of oxygen distribution by employing other excitation wavelengths.

Laser Beam diodes create deep-UV light

Laser beam diodes create deep-UV lightA team of scientists from Japan has manufactured a laser beam diode that allows emitting deep-ultraviolet light. To be more precise, the developed laser system can produce the shortest laser beam wavelength in the world, it is only 271.8 nm under pulsed current injection at room temperature.

It should be noted that previous versions of similar fiber lasers succeeded to achieve emissions only down to 336 nm. The potential applications of the new laser system include disinfection in health care, treating skin conditions, for instance, psoriasis, and analyzing gases and DNA.

The base of the fiber laser system is made of a high-quality aluminum nitride (AlN) substrate that enables to escape of the limitations connected with lower quality AlN. The thing is that the AIN quality is considered to influence the efficiency of a fiber laser diode’s active layer in converting electricity into laser beam light energy.

The team confirms that a quantum well separates p-type and n-type layers in the laser system. The operating principle of the developed fiber laser is based on “electric current that is passed through a laser beam diode, and positively charged holes in the p-type layer and negatively charged electrons in the n-type layer flow toward the center to combine, releasing energy in the form of photons.”

Thus, scientists have developed the quantum well for the fiber laser so that it could produce deep UV light. The p- and n-type layers consist of aluminum gallium nitride (AlGaN). Herewith, every side of the p- and n-type layers in the laser system are surrounded by cladding coatings made of aluminum gallium nitride as well. The cladding is produced by using the process of doping.

Doping is regarded as a way that changes a material’s properties. The team also claims that the aluminum gradient of laser beam diodes increases the flow of positively charged holes. Finally, it was discovered that the technique of the polarization doping of the p-side cladding layer implied that a pulsed electric current of “remarkably low operating voltage” of 13.8 V in the fiber laser system was required for the emission of the UV wavelength.

Nowadays the team of scientists plans to perform advanced joint research to reach continuous room temperature deep-UV lasing for the production of UV-C semiconductor laser system products that can greatly improve the current benefits leading to the appearance of new promising applications in various areas.

Temperature control is crucial for the fiber lasers industry

Temperature control for the fiber laser industryThermal stability plays a crucial role in industrial laser systems. Thus, the developers and manufacturers of fiber lasers have to design them to provide accurate heat regulation. Because inappropriate temperature control can lead to systemic or catastrophic consequences. The thing is that fluctuating temperatures significantly influence the capabilities of fiber laser systems and their lifespan, as well as production outcomes and customer satisfaction.

The risk of premature failures on laser systems increases, to be more precise, in the case of low-temperature control (when electronics are not being cooled properly). Numerous fiber lasers have water-cooled systems (the chiller), and the laser stops operating when any of those components go down. New chiller technologies have been developed to produce a more reliable chiller that fiber laser manufacturers can confidently install into all their systems.

The industry of chilling systems is considered to develop with the demands of the fiber laser industry. “Having a chiller that has the right heat removal, along with excellent stability and a level of quality and maintenance-free operation, is absolutely essential in keeping that fiber laser system up and running, so the customer’s making parts.” And power stability of laser systems is highly important for their reliable operation.

An ineffective chiller is going to have a great impact on a fiber laser with power stability. Additionally, it can influence the laser beam profile that can transform or warp things. In the case of water temperature increase, metal components of laser systems can be moving slightly more than it is required, and it can lead to the motion of the laser beam resulting in higher pointing instability.

The benefits of modern chilling systems for fiber laser systems include:

  • high quality;
  • less downtime;
  • ease of use.

Therefore, such innovations are required and vital in the evolution of the fiber laser industry. Some customers would not like to apply laser systems because of their maintenance that is regarded as the number one reason for failure. Nevertheless, now the problem is solved by a self-changing filter, due to which it is changed for up to two years.

New fiber laser technologies allow the development of a user-friendly recirculating chiller for various applications. Today it is possible to calculate the ideal pump, fluid, and power capacity for the chiller in fiber laser systems. Besides, the developers can produce a chiller considering your budget, herein, it will offer the highest value for customers.

Fiber lasers fight greenhouse gases

Fiber lasers fight greenhouse gases A team of researchers from Switzerland has developed a detecting system consisted of conventional fiber lasers and a photonic chip that allows tracking greenhouse and other gases by the application of a mid-infrared light source. The team uses a commercially affordable fiber laser system and combined it with a waveguide chip. That helps surely to emit laser beam lightwaves in the MIR spectrum.

According to the researchers, the developed laser system based on a new MIR laser beam light source enables them to determine greenhouse, other gases, and, moreover, molecules in a person’s breath. The thing is that the used fiber laser produces light in a specific wavelength range.

The operating principle of the fiber laser system is based on the laser beam that “is directed through a waveguide measuring 1 μm (0.001 mm) across and one-half mm in length. The waveguide can alter the frequency of the light as it passes through.” Herewith, several key aspects of the laser system’s design were improved. Among them are the waveguide geometry and material and the wavelength of the original laser beam source.

Thus, the researchers obtain a fiber laser system that is regarded as simple, yet efficient and reliable. Also, it becomes possible to adjust the wavelength of the laser beam light by tuning the geometry of the waveguide. The laser system is considered to be a turnkey, highly efficient, compact MIR laser beam source. It provides power levels sufficient for spectroscopy applications.

The system has been already tested on the detection of acetylene, a colorless and highly flammable gas, by absorption spectroscopy. The thing is that the fiber laser emits laser beam light in the MIR spectrum, saving 30% of the original signal strength. For instance, the waveguides pumped with a 2-μm fs fiber laser succeded a spectroscopic spectral region in the 3- to the 4-μm range, with up to 35% power conversion and mW-level output powers.

The researchers confirm that the developed fiber laser system sets a new benchmark for efficiency. Moreover, it is the first fully-integrated spectroscopic laser beam source resulting in no need for the laborious process of accurately aligning all the components in a standard laser system.

Finally, it was challenging to transport previous IR fiber laser systems for application since they include complex, damage-prone hardware. Modern laser systems can promote the development of additional miniaturized MIR technologies. It has a wavelength range that scientists rarely get to work with. Additionally, now the researchers have the opportunity to see on-chip detectors that is possible to be easily carried out into the field.
