摘要
报道了激光二极管双向抽运Nd:YVO4晶体、LBO腔内倍频、最大输出功率为5.3W的连续波绿光激光器。采用LBO晶体Ⅰ类非临界相位匹配;NCPM),温度调谐,当抽运光功率为20W时,获得了5.3WTEM00模532nm绿光输出,光光转换效率达26.5%。并对绿光模式及输出功率随LBO晶体温度的变化关系进行了测量,与理论结果符合较好。
Abstract
A maximum of 5.3 W CW output green laser has been obtained by intracavity frequency doubling with LBO in a Nd:YVO4 laser doubly pumped by two laser diodes. With Ⅰ-type noncritical-phase-match (NCPM), temperature tuning of LBO crystal, a maximum of 5.3 W of cw TEM00 mode output at 532 nm has been obtained with 20 W pump power, the optical-optical conversion efficiency is 26.5%. The mode of the green light and the relation between the output power of green laser and the temperature of LBO crystal have been measured, they all agree well with the theoretical results.
