基金项目:江苏省市场监管局科技计划项目资助(项目编号:KJ21125043)(380~1100)nm自由空间输入式激光波长计校准方法研究李凤娇黄万明郭鑫唐小聪陈�尧丁建一张佳瑶(南京市计量监督检测院)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。关键词:波长;相对强度;分辨力DOI:10.15988/j.cnki.1004-6941.2023.8.001ResearchontheCalibrationMethodof(380~1100)nmOpticalWavelengthMeterswithFree-spaceLaserReceivingPortLIFengjiaoHUANGWanmingGUOXinTANGXiaocongCHENQiyaoDINGJianyiZHANGJiayaoAbstract:Atpresent,thereisnorelevanttechnicalspecificationforfull-parametercalibrationoflaserwavemeterinvisibleandnear-infraredwavelengthrange(380~1100).Therefore,inthispaper,thewavelengthaccuracy,spectrumanalysismodule(longitudinalmoderesolution,relativeintensity)andtheresponsewidthofthewavelengthmetertopulsedlaserarestudiedbythefull-parametercalibrationmethod,andastandarddeviceissetupforexperiments.Theresultsshowthatthismethodisfeasible.Keywords:wavelength;relativeintensity;resolution0引言光波长计是用于测量激光的波长值。干涉型光波长计的工作原理是通过将光接收...
