CONTROL METHOD OF PULSE GENERATION MODE OF LASER EMISSION IN LASER UNIT BASED ON SOLID-STATE LASER ON Nd:YAG CRYSTAL WITH DIODE PUMPING OF ACTIVE MEDIUM Russian patent published in 2016 - IPC H01S3/941 H01S3/136 

FIELD: electricity.

SUBSTANCE: implementation of the method involves supply to an amplitude modulator of a pulse low-frequency control voltage relative to activation of power of a laser diode with time delay Δt determined based on the following: Δt≥Δt_min=100(11-5α)t_L, where Δt_min is a minimum value of supply delay time to the amplitude modulator of pulse low-frequency control voltage, t_L is life time of an active centre of laser medium at the upper level of signal transition, and $\alpha =\frac{P_{pump}}{P_{pump}^{thres}}$ is a pumping parameter showing excess pumping power Ppump over the threshold value $P_{pump}^{thres}.$ The range of variation in α value for implementation of an equal bundle of pulses is within 1.6≤α≤2.0.

EFFECT: providing a stable pulse generation mode of laser emission.
