✦ Synopsis

A new resonator design for doubly resonant continuous-wave (CW) cyan laser at 500.8 nm intracavity sumfrequency mixing in double-crystal RTP was reported. 392 mW of cyan laser at 500.8 nm was generated by mixing 1064 nm Nd:YVO4 laser and 946 nm Nd:YAG laser. The beam quality M 2 value was equal to 1.5 in both horizontal and vertical directions at the maximum output power.

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 t
