METHOD FOR STABILIZING ENERGY IN A PULSED SOLID-STATE LASER WITH DIODE PUMP AND ACTIVE Q-SWITCHING Russian patent published in 2023 - IPC H01S3/42 

FIELD: laser radiation.

SUBSTANCE: method for stabilizing the energy in a radiation pulse of a diode-pumped solid-state laser with active Q-switching, the temperature of the pump elements is determined, control signals are generated for thermoelectric modules or heaters, as well as for the pump current pulse shaper. When the temperature of the elements is above the maximum, a signal is generated for thermoelectric modules, when the temperature of the elements is below the minimum - for heaters, at the temperature of the elements, between max and min, establish the relationship between the pump current pulse duration and temperature, as well as the pump current pulse repetition rate, the operating time of the laser in the radiation generation mode, the time interval between pulse trains, and determine the delay time for the formation of the pump current pulse relative to the leading edge of the external control pump sync pulse on pump elements with a given amplitude and controlled duration of the pump current pulse. The temperature, the frequency of the current pulses, the operating time of the laser and the break time are determined cyclically.

EFFECT: energy stabilization in a solid-state laser radiation pulse.
