THERMAL COMPENSATION OF WAVE LENGTH DRIFT FOR LASER OPERATING IN PULSATION MODE Russian patent published in 2019 - IPC H01S5/06 

FIELD: electricity.

SUBSTANCE: invention relates to laser equipment. Essence: laser system contains a laser operating in the pulsation mode and a heater. Laser contains the active layer and is configured to emit an optical signal during the pulsation period. Change in temperature of the laser operating in the pulsation mode leads to a shift in the wavelength of the optical signal. Heater is thermally coupled to the active layer and configured to reduce the wavelength shift of the optical signal during the pulsation period by applying heat to the active layer of the laser based on the temporal parameters of the pulsation period.

EFFECT: technical result: reduction of the shift of the laser wave operating in the pulsation mode.
