一级放大的超短腔染料激光器

Ultrashort cavity dye laser with a one-stage amplifier

一、前言 超短腔染料激光器可产生窄脉冲、可调谐光脉冲输出。但由于其能量较小(～1μJ),它的应用受到限制。本文使用纵向泵浦的一级放大,可获得能量放大20倍左右,稳定性较好的ps激光脉冲,而且超短腔染料激光器光脉冲的时间抖动小,它可作为用于高时间分辨率研究中的探测光。

The short cavity dye laser with a one-stage amplifier is studied. It shows that the amplification factor is about 20 and a considerable reduction in intensity fluctuations can be achieved when a strong, nonsaturable absorber is used in the amplifier.
