NII Polyus: Technology for creating lasers

2024: Technology Development

On February 19, 2024, the Polyus Research Institute named after M. F. Stelmakh holding Shvabe (part of the Rostec state corporation) announced the development of powerful new generation laser emitters. It is expected that such products will find application in medical equipment, automotive autopilot systems, etc.

The author of the project is Maxim Ladugin, Doctor of Physical and Mathematical Sciences. Proposed technology provides for creation of laser quantum-sized structures whose dimensions range from nanometers to several micrometers. The basis is semiconductor compounds of aluminum, gallium and indium with phosphorus and arsenic. These structures are said to be optimal for use in the sought-after spectral ranges of 750-850 nm, 900-980 nm and 1500-1600 nm.

The technology provides a number of advantages over other methods. In particular, it allows you to make the final device more compact, as well as reduce its power consumption. At the same time, it becomes possible to increase the power of laser devices. Products of a new type can be used in various fields - metrology, medicine, ranging, high-speed fiber-optic communication systems, etc. For example, in the field of surgery, more powerful and compact emitters will allow the creation of next-generation laser scalpels for more accurate and efficient operations. Improved lidars can be created for self-driving cars.

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 being created. In particular, on the productivity and compactness of technological installations, rangefinders and medical devices, including surgical and cosmetological ones, - said Evgeny Kuznetsov, General Director of the Polyus Research Institute.[1]
