Laser systems help in studying explosions

Laser Systems in studying explosionsAn explosion is considered to be a complex activity that is characterized by quickly changing temperatures, pressures, and chemical concentrations. There are special infrared laser systems called swept-wavelength external cavity quantum cascade tunable fiber lasers. They offer valuable and never-before-seen information about explosive fireballs.

This fiber laser device is versatile and includes such an advantage as a broad wavelength tuning range that enables it to measure numerous chemical substances as well as huge molecules in an explosive fireball. Researchers confirm that the capability of the laser system to measure and monitor the crucial changes during explosions will favor them to understand and even control the events.

The measurements by the laser system are performed with the help of rugged temperature or pressure probes placed inside an exploding fireball resulting in physical information. Nevertheless, the fiber laser device does not allow measuring chemical changes that may be created during the process of the explosion. Thus, it is possible to make a sampling of the donation end products by the tunable laser system. However, the data information will be presented only after the explosion is over.

The laser system is able to detect molecules in the fireball by controlling the way they interact with light, significantly in the infrared region. It should be mentioned that “these measurements are fast and can be taken a safe distance away”. Herewith, laser systems are essential for these purposes because fireballs are turbulent and contain highly absorbing substances.

The application of a new laser system device measures explosive occurrences at faster speeds, at higher resolutions, and for longer periods than it was possible before using infrared laser beam light. Therefore, now the swept-wavelength external cavity quantum cascade tunable fiber laser offers new measurements due to the combination of the best qualities provided by high-resolution tunable laser system spectroscopy and broadband fiber optic techniques such as FTIR.

The fiber laser system was tested on four types of high-energy explosives, all integrated into a specially developed chamber to contain the fireball. Herewith, a laser beam from the tunable fiber laser is directed through this chamber while quickly changing the laser beam light’s wavelength, then the light is recorded throughout each explosion to measure changes.

Finally, the detailed analysis of the information obtained by the laser system offers the required data about the temperature and concentrations of these substances throughout the explosive case. The tunable fiber laser opens a new way to study explosive detonations that could find other applications. Additionally, it is planned to extend the measurements due to the development of laser technology to more wavelengths, faster scan rates, and higher resolutions in the near future.

Laser technology for military applications

Laser Technology for military applicationsNowadays U.S. Army Infantry receives high threats, while they advance through wooded, rocky terrain to maneuver to contact and “close with the enemy” resulting in facing the most incoming fire of any army unit. This is the main reason why the U.S. Army needs additional protection. The application of laser technology is considered to be a possible solution to the problem.

To be more precise, modern laser technologies can be implemented for the use of pre-shot detection, which means that such laser systems embedded in Army weapons would allow identifying enemy weapons before they are fired. The laser system can detect an optical part of a weapon (glass) directed at a military servant. It should be noted that such an opportunity for laser technology to see a person and detect a shot threat provides a great benefit.

Thus, according to researchers, the laser system technology allows soldiers to find their enemies without first being fired upon, leading to saving human lives and changing military tactics. Nevertheless, these portable laser system emitters are still in development. Herewith, the developed laser technology should be used along with the Army’s existing Rapid Target Acquisition system that applies wireless data links to connect night vision goggles with rifle weapons sights.

Additionally, the application of such laser devices by military servants offers numerous new combat benefits. For example, laser system weapons are used both as an offensive weapon and a “detector” capable of finding targets. Herein, there are scalable laser devices, which means that they are able to collect several laser beams or fire in more narrow configurations offering various options.

The application of the defensive laser system for detection may include soldier-fired offensive laser module weapons. The laser beams are very rapid (they travel at the speed of light), moreover, the laser devices are highly quiet. Therefore, it is possible to fire silently, allowing military servants not to give up their position.

In spite of the fact that weapons based on laser technology are in development stages, they are already used in the following fields of laser application: firing laser devices for army strykers, the weapons system for the Navy, ground-testing laser weapons for the Air Force. A potential application of the laser system includes missile defense and armed drones engineered for space flight.

The use of laser technologies for military purposes has several developmental challenges. The thing is that mobile power sources are required for laser systems to operate, also portable laser devices pose some technical challenges which are necessary to be improved.

Organic fiber laser systems enlarge their applications

Organic Fiber Laser Systems and their applicationsAccording to the last research, now it has become possible to design accessible laser systems that are able to emit laser beams of a wide range of colors resulting in new fields of applications from communications and sensing systems to displays. Thus, researchers from Japan have developed an optically pumped organic thin-film laser module that allows continuously producing laser beam light for 30 ms that is about 100 times longer than previously used laser devices.

Compared to conventional inorganic laser systems (used in CD drives and laser pointers), the principle of organic thin-film laser module’s operation is based on a thin layer of organic molecules as the laser medium that emits laser beams by producing and intensifying light during the excitement of an energy source. Herewith, an intense ultraviolet laser beam light from an inorganic laser system is regarded as the energy source.

Additionally, the organic laser system is highly potential because it offers such an advantage as the opportunity to more easily reach colors that are virtually impossible with inorganic laser devices. It should be noted that “by designing and synthesizing molecules with new structures, laser beam emission of any color of the rainbow is possible.” Although organic thin-film laser systems have been studied for a long time, such features as degradation and loss processes have significantly restricted the duration of laser beam emission.

Nonetheless, the researchers succeeded to overcome the mentioned challenges and enlarge the duration of the laser system process by unifying three strategies:

  • The use of an organic fiber laser medium with triplet excitons that absorb various colors of laser beam light than that produced by the laser system to decrease main losses originating from the absorption of emission by packets of energy.
  • The problem of thermal degradation is solved by manufacturing the laser devices on a crystalline silicon wafer and gluing a piece of sapphire glass on top of the organic laser system medium with a special polymer. The thing is that the silicon and sapphire material, applied in the organic thin-film laser module, are considered to be good heat conductors that reduce the heat level in the laser devices.
  • The strategy of optimization of a frequently used grating structure or mixed-order distributed feedback structure installed under the organic laser system medium to achieve optical feedback, the input energy required to keep the laser devices allows reducing to new lows.

These laser systems can be used in extreme environments, that is why searching for new laser techniques to take away any inefficiencies and prevent laser devices from overheating. Moreover, the combination of the organic laser modules with inorganic ones enables the production of colors that are difficult to create by employing a conventional type of lasers, with applications in process spectroscopy, communications, displays, and sensing systems.

Fiber laser systems do not leave scars after surgery of breast tumors

Fiber Laser Systems do not leave surgery scars Fiber laser system allows women to have surgery for breast tumor removal without scars. The operation takes less than an hour and leaves only a tiny puncture mark. Thus, a new laser system treatment for breast cancer was recently approved for application in the UK, and it is planned to use fiber laser surgery in other countries.

To be more precise, the surgery by the fiber laser system requires just a local anesthetic. Frances Barr from Bristol became one of the first women in Britain to be subjected to a new laser system surgery for breast cancer. Compared to traditional surgery with a general anesthetic, laser technology is based on the use of local anesthetic.

The principle of fiber laser operation is based on a fine, hollow needle that is inserted through the breast tissue into the tumor, herewith, a fiber probe is brought through the needle and a hot laser beam attacks the tumor. It should be noted that after the injection of a local anesthetic into the front of the breast, the doctor applies a handheld ultrasound monitor to guide a needle towards the tumor.

When the tip of the needle achieves it, the fiber laser probe is inserted to defeat the cancerous tissue, herein, the patient is awake during the process. The woman said that she felt some inconveniences when the needle forced its way in, however, this was not painful. The dead tissue was also removed after the laser system surgery and no trace of cancer was left. The laser technology succeeded.

Compared to a lumpectomy procedure, fiber laser treatment does not present any major risks, however, the procedure can not be currently used for breast tumors bigger than 20 mm in diameter. Nonetheless, cancer surgery by fiber laser system is regarded to be particularly effective for older women with small breast tumors who may be less able to stand the traditional surgery. Also, the doctors have to be certain that the laser system treatment removes all cancer.

Every year about 25.000 women in the UK are exposed to a lumpectomy procedure for breast cancer, generally when the tumor has not spread. Conventional techniques are useful, however, leave scars that may become infected (1.5-10%). The new laser technology, in its turn, offers the same results, but without collateral damage because of the tiny size of the entry point.

The surgery by the fiber laser system takes only ten minutes to achieve the required laser beam temperature of 60 °C to 100 °C. Additionally, the laser system has heat fiber sensors that detect enough temperature eliminating the risk of damage to healthy tissue. Finally, only two tiny puncture marks are left, and it is not necessary to keep a patient at the hospital. Herewith, the main benefit of fiber laser treatment is the opportunity to repeat the process if scans reveal it didn’t destroy all of the tumors the first time around.

Fiber laser systems criteria for clinical treatments

Which fiber laser systems suit treatment in clinics best? First of all, it should be noted that a laser system with higher power does not mean the opportunity to do things a much lower power fiber laser system will not. The application of Class 4 laser systems of 0.5 W of power is the ideal solution for laser technology treatment in clinics.

To be more precise, photobiomodulation therapy or low-level fiber laser therapy requires a sufficient quantity of laser beam light energy into injured tissues. The thing is that skin scatters and reflects most of the laser beam light that it is exposed to resulting in great challenges.

Herewith, specific wavelengths of laser beam light energy have the skin penetration ability higher than others. Nonetheless, additional barriers (hemoglobin, oxyhemoglobin, fat, and water) are distinguished under the skin that also catches or reflects more of the remaining laser beam light. Thus, it is necessary to pay careful attention to the choice of therapeutic wavelengths to maximize a fiber laser system’s efficiency.

Also, laser systems with the ideal laser beam wavelengths to penetrate the tissue and a low level of overall power allow efficient treatment of small areas and take 30 minutes or even longer. The possible solution to the low power of fiber lasers and the requirement to treat a large area is substantially increasing treatment time to maintain the necessary dosage.

Such a disadvantage of Class 3b laser systems is considered to be the main reason a lot of early fiber laser research demonstrated amazing results. Compared to Class 3, Class 4 fiber laser systems are used in photobiomodulation, where the previous lasers leave off at 0.5W of laser beam power.

The higher power of laser systems enables “sufficient laser beam energy to be passed onto nerve, muscle, ligament, tendon, and capsular tissue in a reasonable amount of time”. The thing is that the usual therapy session takes from 2 to 6 minutes, which is acceptable in a clinical setting.

Fiber laser systems of high beam quality offer such benefits as the versatility to treat injured tissue in multiple areas in a given session, which greatly improves the overall effectiveness of the laser when adding it to a plan of care. Nevertheless, Class 4 laser systems commonly have a higher cost than Class 3 laser technology.

Finally, it is necessary to take into consideration the following factors when choosing fiber laser products: the laser device manufacturing, warranty parameters, application heads, and a type of available customer service to learn the staff how to use the laser system effectively after it is purchased. Although the fiber laser cost plays a crucial role, careful consideration should be given to the mentioned factors.
