All-Solid-State Continuous-Wave All-Intracavity Sum-Frequency Mixing Blue Laser at 488 nm
摘要
报道了全固态连续波488 nm蓝光激光器,蓝激光分别由Nd:YLF4(Nd:YLF)和Nd:YVO4晶体的1047和914 nm谱线非线性和频产生,实验中采用复合腔结构,利用LiB3O5(LBO)晶体I类临界相位进行腔内和频,当总注入抽运功率为32.2 W(注入到Nd:YLF晶体和Nd:YVO4晶体的抽运功率分别为13.4和18.8 W)时,获得650 mW的TEM00连续波488 nm蓝光激光输出。30 min功率不稳定度优于±2.8％。光束质量因子M2=1.3。
Abstract
An all-solid-state coherent radiation at 488 nm by intracavity sum-frequency generation of 914 nm Nd:YVO4 laser and 1047 nm Nd:YLF4 (Nd:YLF) laser is reported. Blue laser is obtained by using a double cavity and type-I critical phase matching LiB3O5 (LBO) crystal sum-frequency mixing. With total pump power of 32.2 W (13.4 W pump power for Nd:YLF laser and 18.8 W pump power for Nd:YVO4 laser),TEM00 mode blue laser at 488 nm of 650 mW is obtained at last. The power stability in 30 minutes is better than ±2.8%. The M2 factor is 1.3.
