SOLID-STATE PULSED LASER WITH TUNABLE RADIATION WAVE-LENGTH Russian patent published in 1998 - IPC

FIELD: solid-state pulsed lasers, nonlinear optics, distance measurement, optical detection and ranging, atmospheric and water area pollution monitoring laser systems. SUBSTANCE: the laser end reflector is made in the form of a prism-roof, a 90-degree rotator is introduced between the active and electrooptical components, a polarizer is placed near the return parametric mirror, a collecting lens and rotary mirrors are introduced; the pump and optical axis of the electrooptical component are oriented in a definite way relative to the polarizer transmission plane. EFFECT: expanded operating frequency range of mission plane, expanded operating frequency range of radiation pulse repetition, enhanced efficiency and reliability. 1 dwg
