✦ Synopsis

We report for the first time (to our knowledge) a quasi-three-level Nd:Sr3Ga2Ge4O14 (Nd:SGG) laser emitting at 902 nm. An end-pumped Nd:SGG crystal yielded 718 mW of continuous-wave (CW) output power for 17.9 W of incident pump power. Intracavity second-harmonic generation (SHG) in CW mode has also been demonstrated with a power of 116 mW at 451 nm by using a LiB 3 O 5 (LBO) nonlinear crystal. The blue beam quality factor M 2 was less than 1.27. The green power stability was less 5.3% in 4 hour.
