一种激光脉宽压缩技术

A COMPRESSION TECHNIQUE Of LASER PULSE BANDWIDTH

报道了在谐振腔中放置双染料调Q片进行调Q的理论分析、实验装置、脉宽测试方法及其倍频实验.结果表朋,与单调Q片进行调Q相比,可压缩激光脉冲宽度,激光傍频转换效率也有明显的提高.

In this paper, the theoretical analysis, experimental apparatus, testing method and second harmonic generation of the dye Q-switch with two dye Q-switched plates placed inside the laser resonator are reported. The experimental results show that the new technique has more narrow pulse width and higher coversion efficiency of SHG than one dye Q-switched plate.
