Abstract—We report for the first time a continuous-wave (CW) blue radiation at 494 nm by intracavity sum-
frequency generation of 912 nm Nd:GdVO₄ laser and 1079 nm Nd:YAlO₃ (Nd:YAP) laser. Using type-I critical
phase matching LiB₃O₅ (LBO) crystal, 494 nm blue laser was obtained by 912 and 1079 nm intra-cavity sum-
frequency mixing, and output power of 179 mW was demonstrated. At the output power level of 179 mW, the
output power stability is better than 3.5% and laser beam quality M² factor is 1.21.
