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

FIELD: instrument making.

SUBSTANCE: invention relates to laser engineering. Q-switched laser resonator includes an active element and a resonator consisting of two mirrors, one of which is fixedly secured, while second actuator is provided and is rotatable in such a way that in operative position mirrors are parallel. Rotating mirror in original position deployed relative to operating position at an angle φ, drive is a conductive rod having one end secured to a stationary base, while second has possibility of longitudinal displacement and eccentric rests on a rotating mirror so that longitudinal movement of movable rod end mirror could rotate, moving to a working position, wherein conducting rod is connected with their ends through switch to power supply, and angle where W₀ - set angular velocity of rotating mirror at moment of highest resonator Q, J - moment of inertia of mirror rotation, M - torque generated by drive.

EFFECT: technical result consists in increasing reliability and efficiency of laser.
