Abstract

A photochronographic method for measuring the front profile of a laser pulse is described. The method exploits the saturation of an image converter. The dynamic range of these measurements reaches 105 at 1.315 μm, the wavelength of an iodine laser. The relative error of the power measurements is no greater than 20%. The time resolution is no worse than 25 ps per tenfold change in power.

大动态范围亚纳秒激光脉冲前廓线的测量
本文描述了一种测量激光脉冲前轮廓的照相计时法。该方法利用了图像转换器的饱和特性。在碘激光波长1.315 μm处,测量结果的动态范围达到105。功率测量的相对误差不大于20%。时间分辨率不低于每10倍功率变化25 ps。
