Paper Abstract

Anti-laser films have been used for decreasing the intensity of laser to protect human's eyes. Nd:YAG is widely used in military and industry, and its working wavelengths are 532nm and 1064nm. In this paper, we attempted to design a dense film based on a new complex material to improve manufacture efficiency. The frequency-doubling film is G|(HxL)n|A according to the working characteristics of Nd:YAG laser. H4 and SiO2 were selected in consideration of absorption, dispersion, index of refraction, mechanical robustness. x is equal to 2 by optimized the frequency-doubling film (G|(HxL)n |A). The film is fabricated by Leybold SUSPRO-1110 full automatic vacuum coating machine, which is completed with Plasma Ion Assisted Deposition system. UV3150PC spectrophotometer was used to test the spectrum characteristics in the range of 532nm and 1064nm. The testing results showed that the transmission at 532nm and 1064nm are 0.0064% and 0.0041%, respectively. The integral transmission of visibility region is higher than 73%. We can entirely eliminate damages to eyes from Nd:YAG laser by this way.
