二极管侧面泵浦10kHz皮秒激光再生放大器

摘要

采用LD侧面泵浦腔,对SESAM锁模皮秒脉冲中进行再生放大,在10 kHz重复频率下,获得了5.5 W(单脉冲能量0.55 mJ)的皮秒激光输出,光束质量M2 ＜2.9.之后又采用KTP晶体进行倍频,获得了2.25 W皮秒绿光输出.%A LD side-pumped efficient regenerative amplifier is reported. It is seeded from a SESAM mode-locked pico-second laser. A output of 5. 5 W(0. 55 mJ per pulse)at 10 kHz is obtained. The M2 is less than 2. 9. After that,the frequency doubling is done using a piece of KTP,and an output of 2. 25 W at 532 run is obtained.
