摘要

摘要: 当前反卫星激光武器发展迅猛，迫切需要研究和发展卫星的激光防护技术，以增强卫星在空间的生存与防护能力。本文采用可见光-近红外透明和中波吸收的玻璃基底与线性激光防护薄膜相结合的设计方法，在玻璃基板一面设计分光膜，实现1.315 μm波长的反射和0.5~0.8 μm、1.55 μm波段的增透，在玻璃基板另一面设计双波段减反射膜，实现0.5~0.8 μm和1.55 μm波段的增透。采用离子束溅射沉积技术，实现了激光防护窗口薄膜的制备，在0.5~0.8 μm的平均透过率大于96%，1.55 μm的透过率大于98%，1.315 μm的透过率小于0.1%，在2.7 μm的透过率为30%，在3.8 μm的透过率为1.1%。实验结果表明，该方法实现了可见光-近红外-中红外波段激光防护窗口的制备，对于卫星平台防护激光武器具有重要作用。

Abstract: In view of the current development of anti-satellite laser weapons, it is urgent to study and develop laser protection technology of satellites to enhance their survival and protection capabilities in space. In this paper, a glass substrate with transparency in the visible to near infrared wavelengths and absorption in middle infrared wavelengths was chosen, and a linear laser protective film was designed on its two sides. A beam splitter was designed on one side of the substrate and could achieve high reflectivity at a 1.315 μm wavelength and antireflection in 0.5~0.8 μm and 1.55 μm wavelength. Dual-band antireflection film was designed on the other side of the glass substrate and could achieve antireflection in 0.5~0.8 μm and 1.55 μm wavelengths. Using ion beam sputtering deposition technology, a laser protective film window was prepared, achieving the transmittance greater than 96% at 0.5~0.8 μm, greater than 98% at 1.55 μm, less than 0.1% at 1.315 μm, 30% at 2.7 μm and 1.1% at 3.8 μm. The experimental results show that this method is effective in the preparation of laser protection windows in the near-visible mid-infrared band and is very important in the protection of the satellite platforms from laser weapons.
