报道了全固态连续波555 nm激光器。555 nm激光是分别由Nd:YAG和Nd:YVO4晶体的946 nm和1342 nm谱线非线性和频产生,两条谱线在各自晶体对应能级跃迁分别为4F3/2-4I9/2和4F3/2-4I13/2。实验中采用复合折叠腔结构,利用LBOI类临界相位进行腔内和频,当注入Nd:YAG和Nd:YVO4晶体的泵浦功率分别为20 W和10 W时,获得1.06 W的TEM00连续波555 nm激光输出。4小时功率稳定度优于±3.3%。实验结果表明采用两种激光晶体进行腔内和频是获得激光的高效方法,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 CW 555 nm laser was reported. The 555 nm laser is nonlinearly summed at 946 nm and 1342 nm respectively for Nd: YAG and Nd: YVO4 crystals. The corresponding transitions of the two lines in the respective crystals are 4F3 / 2-4I9 / 2 and 4F3, respectively / 2-4I13 / 2. In this experiment, the composite folded cavity structure was used, and the LBOI critical phase was used for intracavity and frequency. When the pumping power of Nd: YAG and Nd: YVO4 crystal was 20 W and 10 W respectively, the TEM00 continuous wave 555 nm laser output. 4 hours power stability better than ± 3.3%. The experimental results show that using two kinds of laser crystals for intracavity and frequency is an efficient method to obtain laser, and can be applied to the other two kinds of laser crystals for intracavity nonlinearity and frequency, to obtain more different wavelength laser output.
