We report for the first time a coherent radiation at 488 rim 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 (LiB(3)O(5)) 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%.
