LASER WITH CONTROLLED GENERATION SPECTRUM Russian patent published in 1995 - IPC

FIELD: electronics. SUBSTANCE: device for pumping of active medium of laser has pumping laser, system of rotary reflecting elements, pumping lens and active medium. Angles of turn of each of reflecting elements about two mutually perpendicular axes and distance between pumping lens and pumped active medium are chosen in compliance with required spectrum of laser generation and needed ratio of intensities of components of generation spectrum. Besides this pumping lens can be manufactured in the form of lenses set independently and reflecting elements can be fabricated in the form of concave mirrors having additional degree of freedom translational motion. EFFECT: enhanced precision of control. 2 cl, 1 dwg
