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.
