PULSED LASER WITH MODULATED Q-FACTOR Russian patent published in 2016 - IPC H01S3/123 

FIELD: optics; instrument engineering.

SUBSTANCE: pulse laser with modulated q-factor has active element and resonator consisting of two mirrors, one of which is rigidly fixed and the second one is equipped with drive and has possibility of rotation so that in working position mirrors are parallel. Laser includes elastic element and brace which fix the second mirror relative to body in initial position at angle φ to working position. Brace is represented by conductive thread and elastic element is installed so that in initial position the brace is stretched counteracting torque moment M created at the second mirror by elastic element. Besides there are series-connected switch and power supply connected to the ends of current-conducting thread, wherein angle is where W₀ is given angular velocity of second mirror in its working position, J is total inertia moment of second mirror and elastic element rotation, M is torque created by elastic element on second mirror element.

EFFECT: higher reliability and efficiency of laser.
