2024: Laser emitters based on semiconductor nanostructures

An employee of the Polyus Research Institute named after M.F. Stelmakh Holding "Schwabe" State Corporation Rostec has developed a technology for producing semiconductor nanostructures, and has also created powerful new generation laser emitters on their basis. This was reported to TAdviser on February 19, 2024 by representatives of Schwabe. The results of scientific work can be used in the production of medical equipment, unmanned vehicles, lidar systems and other devices.

Doctor of Physical and Mathematical Sciences Maxim Ladugin developed the physical foundations for the design of laser quantum-sized structures, the dimensions of which range from nanometers to several micrometers, which ultimately allows you to make the final device more compact, as well as reduce energy consumption. The project was carried out on the basis of semiconductor compounds of aluminum, gallium and indium with phosphorus and arsenic. According to Schwabe representatives, such structures will be optimal for the demanded spectral ranges 750-850 nm, 900-980 nm and 1500-1600 nm and will increase the power of laser devices.

As the general director of the Polyus Research Institute Evgeny Kuznetsov noted, the improved characteristics of near-infrared lasers are extremely important for many areas. For example, for metrology, medicine, ranging, high-speed fiber-optic communication and others.

"In his scientific work, our collaborator demonstrated the results of creating a new generation of high-power laser emitters - laser diodes, rulers and arrays - that operate in pulsed and continuous modes in the infrared spectrum from 750 to 1600 nm. The use of the proposed technologies will make laser emitters more efficient, fast-acting and miniature, which will have a positive effect on the devices created, "said Evgeny Kuznetsov. - In particular, on the performance and compactness of technological installations, rangefinders and medical devices, including surgical and cosmetic. "

Polyus Research Institute develops and produces semiconductor and solid-state lasers and devices based on them, laser gyroscopes, navigation devices, medical installations and other products.
