高质量的激光装置要求各组成部分都达到高精密、高稳定可靠，其中的能量测量是最基本的必测参数之一，测量结果的可靠与否直接影响整个装置的正常工作与调整，并对实验结果的分析具有重要意义． 测量钕玻璃、ＹＡＧ等短脉冲高功率激光的输出能量，国内外大都采用体吸收型能量计 High-quality laser devices require all components to achieve high precision, high stability and reliability, of which the energy measurement is one of the most basic parameters to be measured, the reliability of the measurement results directly affect the normal operation of the device and adjustment, and The analysis of experimental results is of great significance. Measurement of neodymium glass, YAG and other short-pulse high-power laser output energy, the majority of domestic and foreign body absorption type energy meter
