Abstract

The invention discloses a laser protection device doped with dye. The device comprises a polymer layer A and a polymer layer B, polymer molecules in the polymer layer A are arrayed into a left-hand spiral structure and can reflect left-hand polarization lasers, polymer molecules in the polymer layer B are arrayed into a right-hand spiral structure and can reflect right-hand polarization lasers, the polymer layer of the left-hand spiral structure and the polymer layer of the right-hand spiral structure are combined, total reflection on circularly polarized light can be achieved, in addition, dye can absorb incident lasers, and the protection angle of laser protection film can be enlarged. The laser protection film doped with dye is easy to manufacture, large in protection angle and good inflexibility, existing devices can be modified, and the film has good application prospects in the fields such as laser protective eyewear and lamination film of car windows.

Description

technical field [0001] The invention relates to laser protection technology, in particular to a dye-doped laser protection film. Background technique [0002] Laser has the characteristics of high optical power density and good collimation, which will cause damage to eyes and other precision optical equipment; for a long time in the past, laser can only be obtained in special environments such as laboratories and factories, so it is harmful to public environments. The impact on the safety of lasers is minimal, but various small lasers are becoming more and more easy to obtain, and the impact of lasers on public environmental safety, such as road safety, has attracted more and more attention. [0003] At present, many laser protection devices such as absorption type, reflection type, nonlinear absorption type, optical multiplexing technology type, etc. have been developed and applied, but these devices still have many shortcomings, such as complicated manufacturing process, l...
