SINGLE-MODE SOLID-STATE LASER WITH THERMAL STABILIZATION OF THE DIODE PUMP AND PASSIVE Q-SWITCH AND ITS CONTROL DEVICE Russian patent published in 2022 - IPC H01S3/42 

FIELD: lasers.

SUBSTANCE: inventions group relates to diode-pumped solid-state lasers and devices for controlling laser radiation parameters. A single-mode solid-state laser contains an emitter with an optical shutter, a current pulse shaper connected to a control microcontroller, and an optical module for pumping the emitter, as well as series-connected beam splitter plates and a photosensor. The optical pump module is equipped with a diaphragm, and the optical shutter is made passive. The laser control device contains a thermoelectric module with a driver, a heater with a driver, thermal sensors and a control microcontroller connected to the drivers and a current pulse shaper, a photo sensor, the input of which is connected through the beam splitter plates to the output of the active element.

EFFECT: increasing resistance to external influencing factors.
