Tunable green-blue-purple laser

The invention is a tunable green-blue-purple laser. It is a micro-laser device which adopts the red-near infrared tunable laser excited by ª‰-BaB2O4 nonlinear optical crystal frequency-doubling tunable laser crystal Cr3+:LiSr0.8Ca0.2AlF6 to generate the tunable green-blue-purple layer. The used tunable laser crystal is CrxLiSr0.8Ca0.2Al1-xF6 (x=0.05-0.15), and it uses ordinary flash lamp or self-made 593nm wave band all-solid laser pumping source for pumping to generate 700nm-1050nm tunable laser, and then doubles frequency by ª‰-BaB2O4 nonlinear optical crystal to generate 350nm-525nm tunable green-blue-purple laser. 一种可调谐绿-蓝-紫色激光器涉及激光器件领域。阐述一种采用β-BaB#-[2]O#-[4]非线性光学晶体倍频可调谐激光晶体Cr#+[3+]：LiSr#-[0.8]Ca#-[0.2]AlF#-[6]激射的红光-近红外可调谐激光产生可调谐绿蓝紫色激光的小型激光器件。器件中使用的可调谐激光晶体Cr#-[x]LiSr#-[0.8]Ca#-[0.2]Al#-[1-x]F#-[6](x＝0.05-0.15)，阈值低，效率高，用普通闪光灯或是自制的593nm波段的全固态激光泵浦源泵浦即可以产生700nm-1050nm的可调谐激光，然后通过β-BaB#-[2]O#-[4]非线性光学晶体倍频便可以产生350nm-525nm的可调谐绿蓝紫色激光。该器件涉及的光学元件加工精度要求不苛刻。
