| Abstract: | We describe the output performances of the 930 nm 4 F 3/2 → 4 I 9/2 transition in Nd3+:YAlO3 (Nd:YAP) under in-band pumping with diode laser at the 803 nm wavelength. An end-pumped Nd:YAP crystal yielded 1.13 W of continuous-wave (CW) output power for 17.8 W of incident pump power. Moreover, intracavity second-harmonic generation has also been achieved with a power of 172 mW at 465 nm by using a LiB3O5 (LBO) nonlinear crystal. The blue beam quality factor M 2 was less than 1.3. The blue power stability was less 3% in 60 min. |
