利用国产半导体可饱和吸收镜(SESAM),设计了不同的腔型结构,实现了平均功率5 W单路输出,5 W双路输出,输出透过率可调节的半导体可饱和吸收镜线型腔连续锁模(CWML)激光器,双向输出六镜环行腔连续锁模激光器等。将半导体可饱和吸收镜放在腔内的特殊位置,利用一种新的技术方法实现了锁模激光器的频率翻倍。利用由非线性晶体KTP和双色镜构成的非线性镜(NLM),实现了端面抽运Nd∶YVO4激光器的4 W锁模输出。

With a homemade semiconductor saturable absorber mirror (SESAM), different cavities have been designed to achieve mode-locking. Linear cavity continuous-wave mode-locking (CWML) lasers of single output beam with average power of 5 W, double output beams with average power of 5 W and adjustable output transmission have been presented. Bi-directional operation ring cavity passively continuous wave (CW) mode-locked laser end-pumped by a fiber coupled laser diode has been constructed. By placing the semiconductor absorber mirror in a special location, a new mode-locking technique for multiplying the pulse repetition rate of a picosecond passively mode-locking laser was successfully demonstrated. And 4 W mode-locking output of LD end-pumped Nd∶YVO4 laser was achieved by using a nonlinear mirror, which is constituted by a combination of a KTP frequency-doubling crystal and a dichroic mirror with high reflectivity for the second harmonic and partial transmission for the fundamental.
