激光器性能综合测试设备研制

Integrated Test Facility for Performance Parameter of Laser

介绍了激光器的主要性能指标,根据实际需要进行了激光性能测试设备的研究,提出了一种周全的激光性能测试设备研制方案,对该设备的结构设计、光路设计、以及测试方法作了详尽论述。设备中利用两对相互垂直的P分光镜和S分光镜以补偿偏振光在45°面上透反射率不同而造成的测量误差,进一步保证了激光能量测试的准确性。误差分析结果表明该设备满足实际应用中对激光器性能的测试要求。

The performance parameters of lasers are introduced briefly. Based on practical requirement,test facility for performance parameter of lasers is studied, one detailed project is put forward, the design of optical-mechanical structure, optical path, and test methods of the test facility in detail are dissertated. In order to make up for measurement error caused by the different transmittance and reflectance when polarized beam incidence on 45 degrees plane,two pair perpendicular P-spectroscopes and S-spectroscopes are constructed in this test facility,in this way it can improve the veracity of measure of laser energy further. The result of error analysis shows that the test facility can satisfy the test requirements in engineering use.
