We report for the first time a coherent radiation at 488 nm by intracavity sum-frequency generation of 914 Nd:YVO4 laser and 1047 Nd:YLF (Nd:YLiF4) laser. Blue is obtained using doubly folded cavity, type-I critical phase matching LBO (LiB3O5) crystal mixing. With total pump power 32.2 W (13.4 18.8 laser), TEM00 mode blue 1.23 obtained. The stability in 30 min better than 2.8%.
