This paper reports the development of high volume fraction composite-bismuthate glass multilayer films optics Au-mirror with high reflectivity in a wavelength range of 760 to 1000 nm. Multilayer films were fabricated using an radio frequency-magnetron sputtering deposition system. The measured reflectivity of metal plus dielectric films optics Au-mirror could reach up to . Then, on the basis of experiments, a high volume fraction composite-bismuthate glass multilayer optical Au-mirror for a wavelength range of 760 to 1000 nm was manufactured. The tested results indicate that a peak-to-valley value of () was achieved on the Au-mirror surface, and the slope deviation error for the flat surface was lower than root mean square. The surface roughness of multilayer thin films was 1.30 nm (Ra).
