Abstract 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 refl ectance 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.
