摘　　要： 本文采用包含有非线性晶体的四镜8字环形谐振腔结构,通过选取输出耦合镜的透射率和分析铽镓石榴石(TGG)晶体热透镜效应的影响,实现了输出功率达双10瓦级具有相位关联特性的单频连续波1 064/532nm双波长激光器。实验中通过采用透射率为4%的输出耦合镜和长度为20 mm的三硼酸锂(LBO)晶体,实现了输出功率分别为11.30 W和11.23 W的1 064/532nm双波长激光输出,线宽分别为165kHz和330kHz,对应的长期功率稳定性在3小时内分别优于±0.68%和±0.56%,光束质量因子M2均小于1.1。该种具有相位关联特性的双波长激光器可以用来制备稳定的双色光阱和泵浦多个光学参量(OPO)实现多组份纠缠态光场的产生。 Phase correlated continuous-wave（CW）single-frequency dual-wavelength 1 064/532 nm laser with both 10-W-level output power is presented in this paper.By choosing the transmission of the output coupler and analyzing its influence on the thermal focal length of the terbium gallium garnet（TGG）crystal,a figure-eight-shaped ring cavity including a nonlinear crystal is designed and a phase correlated dual-wavelength 1 064/532 nm laser is achieved.When the output coupler with transmission of 4% at 1064 nm and the nonlinear crystal LiB3O5（LBO）with the length of 20 mm in the experiment,aphase correlated single-frequency dual-wavelength laser with output power of 11.30 Wat 1 064 nm and 11.23 W at 532 nm is realized simultaneously.The measured long-term stabilities of 1 064 and 532nm laser for 3hours are better than ±0.68% and ±0.56%,respectively.The measured beam quality M2 of 1 064and532 nm lasers both are less than 1.1.The obtained phase correlated dual-wavelength laser can be utilized to generate the stable dual color optical trap and to pump multiple OPO to generate multi-partite entangled states,respectively.
