激光功率和能量计量技术的现状与展望

Status and Prospect of Laser Power and Energy Metrology

摘要: 功率和能量是激光器的两个基本参数,激光功率和能量测量一直是激光参数计量中最基础的测量工作.总结了美国标准技术研究院(NIST)、英国国家物理实验室(NPL)以及中国国家计量院(NIM)在激光功率能量计量方面的技术现状,重点介绍了国防科工委光学计量一级站激光功率能量计量方面已具备的条件,详细说明了所采用的测量原理以及所达到的测量范围和测量不确定度等技术指标.提出了激光功率和能量计量的发展趋势和发展方向.

Abstract: Power and energy is the two basic parameters for laser, the measurement for these two parameters is the most basic work for laser parameter metrology. We summarize the status quo of NIST of America,NPL of England and NIM of China,and show in detail the specification our Optic Metrology Station has possessed, which include the measurement theory, measurement range and measurement uncertainty. The development direction for laser power and energy metrology is given in the end.
