脏外染料被动压缩准分子激光的输出脉冲特性研究

Study of output pulse properties of extracavity dye passive compression of excimer laser

用紫外染料PTP、BPBD、t-B_uPBD等对XeC1准分子激光施行腔外被动压缩,获得了压缩比为3的XeC1激光脉冲透射输出和压缩比大于8的染料辐射输出。提出“光子传输速率方程”来描述被动压缩现象,计算机模拟计算结果较好地解释了准分子激光压缩及染料辐射的实验结果。

With UV dyes of FTP, BPBD, t-Bu PBD, the extracavity passive compression of XeCl laser pulses produced XeCl laser transmitted pulses with compress-ion ratio of about 3 and dye emission pulses output with tkat of larger than 8 . A 'Pkotom Transport Rate Equatioa'was submitted to describe such phenomenon of pas- sive compression. The computer simulation calculations are coincided approximately with the experiment results of excimer laser compression and stimulated dye emission.
