利用KTP晶体实现1.08 μm Nd:YAP激光器锁模
Mode-Locking of a Nd:YAP Laser at 1.08 μm Wavelength with a Single KTP Crystal
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1.08 μｍ Nd: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1.08 μm出2.4 mJ,二次谐波0.54 μm输出0.5 mJ(同样条件下的静态输出为2.5 mJ),基波脉冲的平均脉宽为40 ps.
Abstract
In this paper, passive mode-locking of a Nd:YAP laser at 1.08 μm using a nonlinear mirror formed by a KTP crystal and a dichroic mirror is described. Experiments demonstrate the superiority and potentials of this mode-locking technique over the mode-locking with saturable adobers. The mode-locked output energy of 2.4 mJ at 1.08 μm and 0.5 mJ at 0.54 μm are measured (In free state, it is 2.5 mJ at 1.08 μm). Its average pulse-duration is 40 ps at 1.08 μm.
