DEVICE FOR STABILISING LASER RADIATION PARAMETRES OF LONGITUDINALLY PUMPED SOLID-STATE LASER Russian patent published in 2009 - IPC H01S3/02 

FIELD: physics; optics.

SUBSTANCE: invention relates to laser technology and can be used in machine-building, optical communication and medicine. The device has an optical pumping module, active element, thermoelectric module, thermoelectric module driver, microcontroller and a first thermal detector. The device also has a second thermal detector, photosensor, and a photosensor signal amplifier. The optical output of the optical pumping module is connected to the optical input of the active element and the optical input of the photosensor, the first output of which is thermally connected to the input of the second thermal detector. The second output is connected to the input of the photosensor signal amplifier, the output of which is connected to the first input of the photosensor signal amplifier, the output of which is connected to the first input of the microcontroller, the second input of which is connected to the output of the second thermal detector. The third input is connected to the output of the first thermal detector, the input of which is thermally connected to the output of the active element. The output of the microcontroller is connected to the input of the thermoelectric module driver, the output of which is connected to the input of the thermoelectric module, the output of which is thermally connected to the input of the active element.

EFFECT: wider functional capabilities, more specifically provision for simultaneous stabilisation of several laser radiation parameters of a longitudinally pumped solid-state laser.
