Ante Laser (Guangzhou) Co Ltd, G uangzhou 510730, ChinaAbstract:An LD end-pumped Nd: GdV04, KTP Intra-cavity frequency doubling Green Laser at 531.7 nm is reported. Using simple compact fiat-concave cavity, 531.7 nm continuous green laser is obtained by 1 063.4 nm Intra-cavity frequency doubling with KTP crystal. When the incident pump power is about 12 W, the stable output power of 372 mW was achieved at 531.7 nm. The optical-to-optical conversion efficiency is up to 3. 1% and the power fluctuation is less than ± 1.2% for 0. 5 h.[著者文摘]
