一、前言激光辐射强度的监测,无疑是激光研究和应用中不可缺少的手段。这种类型的仪器总要有转感器(光能到电能的转换)和信号处理器(信号的放大和处理)两大部分。就转感器的工作机理而言,大致有光电式和量
I. Introduction Laser radiation intensity monitoring is undoubtedly an indispensable tool in laser research and application. This type of instrument always have sensors (light to power conversion) and signal processor (signal amplification and processing) in two parts. In terms of the working mechanism of the sensor, there is roughly a photoelectric type and volume
