✦ Synopsis

We report for the first time a coherent radiation at 488 nm by intracavity sum-frequency generation of 914 nm Nd:YVO 4 laser and 1047 nm Nd:YLF (Nd:YLiF 4 ) laser. Blue laser is obtained by using a doubly folded cavity, type-I critical phase matching LBO (LiB3O5) crystal sum-frequency mixing. With total pump power of 32.2 W (13.4 W pump power for 1047 nm Nd:YLF laser and 18.8 W pump power for 914 nm Nd:YVO 4 laser), TEM 00 mode blue laser at 488 nm of 1.23 W is obtained. The power stability in 30 min is better than 2.8%.
