METHOD FOR CONVERSION OF LASER BEAM FREQUENCY

摘要

FIELD: laser location, communication, processing, information storage and transmission, laser equipment for high- precision processing, medical devices. SUBSTANCE: device has non-linear crystal which is located in con-focal plane of mirrors. In addition device has two coated plates which are mounted on both sides of non-linear crystal at angle of alpha and <EMI ID=0.176 HE=6 WI=12 TI=CHI> to line which connects centers of mirrors. Coated plates are mounted for rotation about this axis in parallel to this line. Angles which are shaped by normal to plate surface and this line are located in same plane. EFFECT: increased functional capabilities. 1 dwgf
