1.5 W cw Frequency-stabilized and Intracavity Frequency-doubled Ring Laser End-pumped by Diode Laser
摘要
光纤耦合激光二极管(LD)抽运Nd:YVO4激光晶体,采用KTP晶体腔内倍频,在输入抽运功率为11 W时,获得1.5 W稳定单频绿光输出,光-光转换效率13.6%.通过边带锁频系统将基频激光频率锁定在F-P共焦参考腔的中心频率上,输出的倍频光频率稳定性优于620 kHz,功率稳定性优于±1.5%.
Abstract
A cw frequency stability and intracavity frequency doubled ring Nd∶YVO 4/KTP end pumped by a laser diode through fiber coupling is designed and experimentally demonstrated. Using the side band frequency locking technique, up to 1.5 W green output with the frequency stability better than 620 kHz is achieved by the pump power of 11 W. The conversion efficiency from light to light is 13.6% and the fluctuation of output power is less than ±1.5%.
