A dye-doped laser protective film is disclosed, comprising a polymer layer A and a polymer layer B. The polymer molecules in the polymer layer A are arranged in a left-handed helical structure which can reflect a left-handed polarized laser. The polymer molecules in the polymer layer B are arranged in a right-handed helical structure which can reflect a right-handed polarized laser. The combination of the polymer layer having the left-handed helical structure and the polymer layer having the right-handed helical structure can completely reflect circularly polarized light. In addition, the dye can absorb incident laser, so as to expand the protection angle of the laser protective film. The dye-doped laser protective film of the present disclosure has a simple manufacturing process, large protection angle and good flexibility, and can refit existing devices. Thus, the dye-doped laser protective film of the present disclosure has a good application prospect in many fields such as laser goggles, window films and the like.
