【摘要】 本文描述了利用ＫＴＰ晶体和腔的基波输出镜构成非线性镜实现１．０８μｍＮｄ：ＹＡＰ激光器的被动锁模．实验表明，这种新的锁模技术比用染料作可饱和吸收体的被动锁模技术有很多突出的优点，具有很大的发展潜力．实验测得锁模时基波１．０８μｍ出２．４ｍＪ，二次谐波０．５４μｍ输出０．５ｍＪ（同样条件下的静态输出为２．５ｍＪ），基波脉冲的平均脉宽为４０ｐｓ．更多还原

【Abstract】 In this paper,passive mode-locking of a Nd: YAP laser at 1. 08 μm using anonlinear mirror formed by a KTP crystal and a dichroic mirror is described. Experimentsdemonstrate the superiority and potentials of this mode-locking technique over the modelocking with saturable adobers. The mode-locked output energy of 2. 4 mJ at 1. 08 μmand 0. 5 mJ at 0. 54 μm are measured (In free state, it is 2. 5 mJ at 1. 08 μm). Itsaverage pulse-duration is 40 ps at 1. 08μm.更多还原
