Low-energy nanolaser system offers new opportunities

on December 21, 2018

Laser systems are used in every sphere of human life. The fields of their application are not limited and include laser cutting, drilling, fast optical data transmissions, medical operations and market, scientific research, biotechnology etc. Nevertheless, now there is a need to develop a scientific laser system that will have low cost, compact size and small power-consumption.

This is the main reason for creation of novel low-energy nanolaser system that is able to shine in all directions. The laser module is considered to open new visions for further potential applications because the key element of omnidirectional light emission is the use of irregularities in the materials that was undesirable for science researches before.

It should be mentioned that such irregularities and imperfections cannot be avoided because of the limit in control process but properly contained disorder can be highly useful for the development of new physical concepts and fields of application for scientific laser systems. The low-energy nanolaser is able to produce omnidirectional light thanks to a low degree of this disorder.

Nanoscale laser systems are thinner than a human hair and now it is very perspective field for scientific research. Traditional fiber lasers use photons that are multiplied in a medium that is located inside a cavity and every photons have the same characteristics.

The other type of laser systems is the polariton laser that does not clone photon but creates non-identical one. The main advantage is low lasing threshold that expand the potential opportunities but its main problem is the need for operation at quite low temperatures.

Nowadays novel nanoscale polariton laser system is able to operate at ambient temperature. Also this type of laser can use not only organic materials that allow obtaining polariton laser emission at ambient temperature but metallic nanoparticles instead of mirrors as in conventional laser modules.

The researchers consider that low-energy nanolaser can find a lot of applications due to its advantages. This laser is much brighter and better defined than a light-emitting diode (LED) and can replace it in microscopy lighting. Nanoscale laser module can be potentially used in Laser Imaging Detection and Ranging (LIDAR) that usually has several conventional lasers and fast moving mirrors for covering vast areas. New omnidirectional laser system is less complicated because does not have the moving mirrors in it. One more way of application is general illumination.

Optromix is a fast-growing fiber laser manufacturer and a vendor of optical fiber sensors and optical monitoring systems. The company offers fast turnkey solutions and creates sophisticated fiber laser systems for special purposes. Optromix uses only its own technologies and develops a broad variety of high beam quality fiber lasers.
