Abstract

A laser-pulse generator for the transfer of continous-wave (cw) absolute radiometric calibrations to high-speed pulse photodetectors is described. The cw input lasers are modulated by a spinning polygon mirror in a ring cavity to produce high-speed, constant-amplitude, constant-shape laser pulses. Constantamplitude outputs range temporally from cw to 15-ns full-width at half-maximum (FWHM) Gaussian pulses. An all-reflective optical design permits operation of the device from the visible to the far-infrared spectral regions. Design and performance estimates for the pulse generator as well as experimental verification are presented.

摘要

描述了一种用于将连续波（cw）绝对辐射校准传输到高速脉冲光电探测器的激光脉冲发生器。连续波输入激光器由环形腔中的旋转多面镜调制，以产生高速、恒定幅度、恒定形状的激光脉冲。恒定幅度输出在时间上范围从连续波到半高宽（FWHM）为15纳秒的高斯脉冲。全反射光学设计允许该装置在从可见光到远红外光谱区域内运行。给出了脉冲发生器的设计和性能估计以及实验验证。
