一、概述本文介绍的激光中功率计检定装置,主要用来检定激光中功率标准——圆盘中功率计,也适用于一般无光谱选择性的激光中功率计的检定。在检定中采用水冷却砷化镓光分束器分光,并用圆盘中功率计来监视CO_2激光器功率起伏。装置由CO_2激光器、遮光板、砷化镓光分束器、锥形标准中功率计以及监视功率变化用的圆盘中功率计等部件组成。二、装置激光中功率检定装置如图1所示。 CO_2激光器:在本装置中要求CO_2激光器输出波长为10.6μm,输出功率约为30瓦,功
First, an overview This article describes the laser power meter calibration device, mainly used to test the laser power standard - the disk power meter, also applies to the general non-spectral selectivity of the laser power meter test. In the test using water-cooled gallium arsenide beam splitter, and disc power meter to monitor CO_2 laser power fluctuations. Device consists of CO_2 laser, shading plate, gallium arsenide beam splitters, cone-shaped standard power meter and monitoring power changes in the disk power meter and other components. Second, the device laser power verification device shown in Figure 1. CO_2 laser: In this device, the output wavelength of CO_2 laser is 10.6μm, the output power is about 30W,
