Test and analysis of optics thin film lossJI Yi-qin, CUI Yu-ping, LIU Hua-song, ZONG Jie, SONG Hong-jun, HONG Wei, JIANG Fu-hao, SUN Chi-quan （1.Tianjin Jinhang Institute of Technical Physics, Tianjin 300192, China; 2.Beijing Automation Control Equipment Institute, Beijing 100074, China;3.Representative Office in Tianjin of Military Representatives Bureau of NED in Tianjin, Tianjin 300192, China）Abstract:With the development of laser standard systems and laser high precision measurement systems,the ultra-low loss thin film technology has been activated and developed. In order to control the magnitude and the distribution of various loss components, it is necessary to test and analyze the whole loss of optical thin film. In this paper, high reflective （HR） and anti-reflective （AR） films were coated on supersmooth substrates with the Dual Ion Beam Sputtering （DIBS）. The coating technological method and parameters were also reported. The whole loss of thin film was measured with the time attenuation method and frequency scanning method, respectively. The test results at 632.8 nm wavelength indicate that the absorption of the HR film is 19.6×10^6, its reflectivity reaches 99.996 86%, and the whole loss of the AR film is 78×10^6. Finally, the composition of the whole loss of thin film and the improvement of its technology were discussed..[著者文摘]
