摘要
报道了激光二极管抽运下的高效率Yb:YGG连续及锁模激光器。实验中采用光学浮区法生长的高质量Yb:YGG激光晶体,在6.7 W的入射抽运功率下得到了1.95 W的激光输出,光-光转换效率为29.1%,最大斜率效率为60%。用半导体可饱和吸收镜启动锁模,在没有补偿色散的情况下得到了1 W的激光输出,光-光转换效率为18.2%,脉冲宽度为2.1 ps,中心波长位于1035 nm。
Abstract
An efficient laser diode-pumped Yb:YGG laser is demonstrated by using a high quality Yb:YGG crystal grown by optical floating zone method, output power up to 1.95 W has been obtained under incident pump power of 6.7 W, corresponding to optical-to-optical efficiency of 29.1% and maximum slop efficiency of 60%. By using a semiconductor saturable mirror absorber (SESAM) to start and sustain the mode-locking, stable laser pulses of 2.1 ps has been obtained without dispersion compensation. The central wavelength is 1035 nm and the output power is 1 W, corresponding to optical-to-optical efficiency of 18.2%.
