| Abstract: | We report for the first time a continuous-wave (CW) coherent radiation at 480 nm by intracavity sum-frequency generation of
900 nm Neodymium Doped Strontium and Lanthanum Aluminate (Nd:ASL) laser and 1030 nm Yb:Y3Al5O12 (Yb:YAG) laser. Blue laser is obtained by using a doubly cavity, type-I critical phase matching LiB3O5 (LBO) crystal sum-frequency mixing. With total pump power of 28.6 W, the blue laser at 480 nm of 170 mW is obtained. At the
output power level of 170 mW, the blue power stability is better than 4.7% and laser beam quality M
2 factor is 1.43. |
