和频黄光激光器研制

Sum-Frequency Yellow Light Laser

研制了全固态连续波555nm黄光激光器,黄激光由Nd:YAG和Nd:YVO4晶体的946nm和1342nm谱线非线性和频产生,两条谱线各自晶体对应的能级跃迁分别为4F3/2-4I9/2和4F3/2-4I13/2。实验中采用复合折叠腔结构,利用KTP晶体II类临界相位进行内腔和频,当注入到Nd:YAG和Nd:YVO4晶体的泵浦功率分别为20W和10W时,获得1.1W的TEM00连续波555nm黄激光输出。实验结果表明采用Nd:YAG和Nd:YVO4两种激光晶体进行腔内和频是获得黄激光的有效方法。

The all-solid-state continuous wave 555 nm yellow laser is reported,yellow laser from Nd： YAG and Nd： YVO4 crystal 946 nm and 1342 nm frequency spectrum and a non-linear,two spectrum Crystal line their corresponding level transitions were 4F3/2-4I9/2and 4F3/2-4I13/2.Experimental use of folded cavity structure,Yellow laser at 555nm is obtained by using a doubly folded-cavity,type-II critical phase matching KTP crystal intra-cavity sum frequency mixing by 1342nm and 946nm,with incident pumped power of 20W in Nd：YAG and 10W in Nd：YVO4,TEM00 mode Yellow laser at 555nm of 1.1W is obtained at last.Experimental results show that the use of Nd：YAG and Nd：YVO4 two laser and two crystals is receives the yellow laser efficient way.
