QUANTUM GENERATOR (LASER) WITH OPTICAL PUMPING (VERSIONS) Russian patent published in 2017 - IPC H01S3/16 

FIELD: physics.

SUBSTANCE: optically pumped laser includes an optically coupled pump radiation source, an active material, a resonator, an input window for introducing pumping radiation, and an output window for outputting radiation to the outside. The laser also comprises an active material cooler and a pressure module configured to uniaxially compress the active material. The active material is a single crystal silicon containing a donor impurity of magnesium with a concentration of 10¹⁴-10¹⁶ cm^-3. The resonant surface of the active material can perform the resonator function.

EFFECT: providing the possibility of reducing the threshold pumping power and achieving a continuous laser generation mode in the terahertz frequency range.
