✦ Synopsis
Intracavity type-I sum-frequency mixing of 1:06 m and 532 nm with a (Â; ') = (106 • ; 77:2 • )-cut YCOB crystal was performed in a compact laser-diode-pumped solid-state laser. Three type-II phase-matching KTP crystals with di erent length were used to generate 532 nm light by frequency-doubling of 1:06 m. The 355 nm output power was measured with the three KTP crystals for Q-switched and continuous-wave (CW) operation, respectively. The maximum ultraviolet output power of 1305 W was obtained with a 15 mm KTP crystal for CW operation, while the maximum ultraviolet average output power of 124 mW was obtained with a 10 mm KTP crystal for Q-switched operation.
