A general system for laser wavelength measurement
【摘要】 本文报道了一个可测量连续与脉冲激光波长的通用激光波长测量系统.系统主要包括一台光栅光谱仪和一台光学多道分析仪.运用低密度光栅并工作在高衍射级次,在输出谱面处He-Ne激光线和被测激光谱线的间距由光学多道分析仪的列阵实时读出,激光波长由个人计算机给出,精度达 0.01.文中给出对精度的分拆.
【Abstract】 In this paper we report a general system for measuring wavelengths of lagers, both CW lasers and pulse lasers. The system consists of a grating spectrometer and a one-dimension optical multichannel analyser. We use a low-density grating and operate in high-order diffraction. The distance between the He-Ne laser line and the laser line to be measured on the output spectral plane is read out in real time by the array of the OMA, the laser wavelength is then calculated by a personal computer with an error of 0.01 A. An analysis on the error is presented.
