FIELD: energy.
SUBSTANCE: method and realising devices, are based on peculiarities of semiconductor laser emitters, consisting in fact that with increase in temperature of radiator for maintaining output parameters (power, radiation force) at required for operation level is necessary to increase operating current at reduced temperature of radiator is necessary to reduce operating current. Voltage at capacitive energy storage unit varies when measuring temperature of the radiator at preset law, which provides passage through radiator pumping current required to maintain radiation power in required for operation range.
EFFECT: technical result is simplification of method and device for pumping semiconductor laser emitter, which provide maintenance of radiation power within certain limits at action of destabilising factor of temperature.
