Abstract

Passive mode locking of a cw lamp-pumped Nd:YLF laser with the nonlinear mirror technique is reported. Nearly transform-limited pulses of 13-ps duration and 1.5-W average power at 1.047 microm have been obtained. The nonlinear mirror consists of a lithium triborate frequency-doubling crystal and a dichroic mirror with high reflectivity for the second harmonic and lower reflectivity for the fundamental frequency. The mode-locking process is self-starting, with pulse duration and stability strongly dependent on the cavity parameters.

摘要

报道了采用非线性镜技术对连续波灯泵浦Nd:YLF激光器进行被动锁模。在1.047微米波长处获得了脉宽为13皮秒、平均功率为1.5瓦的近变换极限脉冲。非线性镜由一个硼酸锂倍频晶体和一个对二次谐波具有高反射率而对基频具有较低反射率的二向色镜组成。锁模过程是自启动的，脉冲持续时间和稳定性强烈依赖于腔参数。
