战场上激光**的不断发展对激光防护提出了更高的要求.由于VO2薄膜的相变温度接近室温,具有良好的光电性能,成为相变材料中最有希望用于红外探测器的激光防护材料.介绍了VO₂薄膜的光电特性,并探讨了其在激光防护应用方面的相关问题以及发展前景.

In the war field, the laser weapon has a higher request to laser protection with its constant development. A new kind of laser protection material the VO₂ thin films is introduced,which based on nonlinear optical phase transition principle. Because the phase transition temperature of VO₂ thin films is near to the room temperature and its optical and electrical properties are very good,VO₂ thin films have become the most hopeful laser protection materials for infrared detectors in phase transition materials.In this paper,optical and electrical properties of VO₂ thin films are introduced.Associated problems and developing trend of laser protection with VO₂ thin films are also described.
