| Abstract: | We have analyzed the stability of a high-power diode-side-pumped intracavity-frequency-doubled CW Nd:YAG laser. It is found that large green power fluctuations observed experimentally are suppressed by compensating thermal lensing of the nonlinear crystal KTP and that of the Nd:YAG rods with an advanced resonator design. Stable CW green powers of 27 W with a beam quality of M2=8 and 16 W with M 2=1.2 (TEM00-mode) were generated |
