FIELD: laser engineering; lasers for instrumentation engineering and optical communications.
SUBSTANCE: proposed laser has housing, optical pumping module, and laser resonator. Laser resonator has case accommodating cylindrical cell with output mirror and active element. Active element is inserted in calibrated bed wherein it is set on heat-transfer adhesive compound. Bed is arranged in cylindrical cell on end of optical pumping module .Thermoelectric module is disposed on butt-end of resonator case on calibrated bed side. Thermoelectric module is coupled with cylindrical cell through resonator heat sink. Heat-insulating spacer is disposed between cylindrical cell and resonator case. Laser is provided with temperature controller and temperature-sensitive element. Control inputs of temperature controller are connected to outputs of temperature-sensing element and outputs, to inputs of thermoelectric module.
EFFECT: enhanced stability of laser radiation within wide temperature range.
