Research progress of VO2 thin film as laser protecting material

With the development of laser technology, the battlefield threat of directional laser weapons is becoming more and more serious. The blinding and destruction caused by laser weapons on the photoelectric equipment is an important part of the current photo-electronic warfare. The research on the defense technology of directional laser weapons based on the phase transition characteristics of VO₂ thin films is an important subject. The researches of VO₂ thin films are summarized based on review these points: the preparation methods of VO₂ thin films, phase transition mechanism, phase transition temperature regulating, interaction between VO₂ thin films and laser, and the application prospect of vo₂ thin film as laser protecting material. This paper has some guiding significance for further research on the VO₂ thin films in the field of defense directional laser weapons.
