Summary:The invention relates to a 200 kilowatt-classed quasi-continuous frequency-doubled high-power green laser with two rods series connected with intracavity. It adopts the side-pumped Nd: YAG crystals of the same type of diode laser pumped component controlled by the same driver. It forms a stable 1064-based depolarized fundamental radiation in the folded resonator designed through the optimization of computer's simulation. It eventually achieves a 203.5W output of 532nm green laser with a conversion efficiency of 72.7% through the double-frequency by HGTR - KTP crystals, and dual acousto-optic Q technology and thermally-induced birefringence compensation technology.
