全固态连续波583nm黄光激光器

All Solid-State Continuous-wave Yellow Laser at 583 nm

报道了全固态连续波583 nm黄光激光器,黄激光是分别由Yb∶YAG和Nd∶GdVO4晶体的1 030 nm和1 341 nm谱线非线性和频产生,两条谱线在各自晶体中对应能级跃迁分别为4F3/2-4I9/2和4F3/2-4I13/2.实验中采用复合腔结构,利用KTPⅡ类临界相位进行腔内和频,当注入到Yb∶YAG和Nd∶GdVO4晶体的泵浦功率分别为12 W和8 W时,获得440 mW的TEM00连续波583 nm黄激光输出。实验结果表明:采用两种激光晶体进行腔内和频是获得黄激光的高效方法,并可以应用到其它两种激光晶体进行腔内非线性和频,获得更多不同波长激光输出。

An all solid-state continuous-wave yellow laser at 583 nm made by nonlinear sum frequency of 1 030 nm and 1 341 nm lasers was presented,1 030 nm wavelength was obtained from ^4F3/2-^4I9/2 transition in Yb∶YAG and 1 341 nm wavelength was obtained from ^4F3/2-^4I13/2 transition in Nd∶GdVO4.TEM00 mode yellow laser of 440 mW at 583 nm was obtained by using a double cavity,type-Ⅱ critical phase matching KTP crystal intracavity sum frequency mixing to 1 030 nm and 1 341 nm,and incident pumped power of 12 W in Yb∶YAG and 8 W in Nd∶GdVO4.The experimental results show that the intracavity sum-frequency mixing is an effective method for 583 nm laser and it can be applied to other two laser crystals to obtain more all-solid-state lasers with different wavelengths.
