| Abstract: | Studies on both how to realize the operation of quasi-three-level system ofNd:YAG 946nm laser and emission of 473nm blue laser at room temperature is presented and constructed.Continuous-wave output power of more than 120mW and slope efficiency near 10% are obtained.Intracavity frequency doubling by using a KNbO3 crystal has been demonstrated in a non-optimized cavity and improvement is possible with a more efficient periodically poled LiNbO3 (PPLN) waveguide. |
