METHOD OF CONTROLLING SOLID-STATE LASER WITH PASSIVE Q-SWITCHING

摘要

The invention relates to a laser technology, in particular to methods and devices for controlling parameters of laser emission and can be used in development of medicine lasers, atmosphere monitoring, in range finding, fiber systems if information transmission and in scientific researches. The invention is aimed at controlling, that is stabilizing emission output parameters, more definite, a number of generating pulses in a group, group repetition frequency of sold-state laser with diode pumping with simultaneous compensation or minimization influence on their parameters of the external environment changes (temperature, pressure) without thermostabilization. A method for controlling output parameters of a solid-state laser with a passive Q-switch comprises control of the emission output parameters by means of a photo-receiving device and adjustment of amplitude and pulse duration of pumping current. At the fixed pumping current duration gradual increase of the pumping current amplitude is gradually started until reaching laser the predetermined regime, the given value of the pumping current amplitude is fixed and then at the fixed pumping current the adjustment pulse duration of the pumping current is carried out while changing the given output parameters of the laser emission until laser output to the predetermined regime or at the fixed value of the pumping current the pumping current amplitude is adjusted.
