中文摘要：

设计了一种新型大功率超短脉冲激光器，将两种传统产生超短脉冲的方法（调Q和锁模）有效的结合起来，并对激光器的各个环节的设计作了说明。为了获得更大的功率采用了电光“腔倒空”直腔调Q法和LDA侧面泵浦，为了获得脉宽更窄的超短脉冲采用了半导体可饱和吸收镜（SESAM）锁模技术。

英文摘要：

One kind of new high efficiency ultra short pulse laser has been designed. Two traditions the ultra short pulse method that is to move Q and mode locking has been combinated effectively and has given the explanation to the laser each link design. In order to obtain a bigger power to use the electric light ＂the cavity empty＂ the straight tune Q and the LDA side pump and in order to obtain a pulse width narrower ultra short pulse to use the semiconductor to be possible to absorb the mirror （SESAM） mode locking technique saturated.
