摘　　要：目前,针对可见光及近红外波长范围(380~1100)nm激光波长计的全参数校准尚未有相关的技术规范。因此,本文对激光波长计的波长准确性、频谱分析模块(纵模分辨力、相对强度)以及波长计对脉冲激光的响应宽度进行全参数校准方法研究,并搭建标准装置进行实验。结果表明:该校准方法具有可行性。At present,there is no relevant technical speification for full-parameter calibration of laser w avemeter in visible and near-infrared wavelengh range(380~1100).Therefore,in this paper,the wavelength accunacy,spectrum analysis module(longitudinal mode resolution,relative intensity)and the response width of the wave-length meter to pulsed laser are studied by the full-parameter calibration method,and a standard device is set up for experiments.The results show that this method is feasible.
