Abstract

High power green laser has a lot of application. We have got 34.2-watt average power of laser at 532nm from a intracavity frequency doubled YAG laser. KTP crystal was used as the frequency doubler. The advantage of Quasi-CW pumping for frequency doubling was taken, the output power of harmonic wave with Quasi-CW pumping is higher than CW pumping. The influence of the polarization property of YAG laser on frequency doubling efficiency was theoretically analysed, and the optimum orientational angle for frequency doubling crystal was found inaddition to the traditional phase matching condition. Some experimental work, the parameters and properties of the laser was reported.
