Paper Abstract

The paper aimed at the problem that strong absorption in visible wavelengths and equipment or operator injury caused by specular reflection exist in infrared laser protection technology to propose an infrared laser non-specular reflection optical micro-structure formed from optical window surface. It has the function of little effect on visible light transmission and large-angle scattering to 1064nm infrared laser in order to enable laser protection. The paper uses light track method to design double-side micro-cylindrical lens arrays with dislocation construction. Array period T and curvature radius of lens units R should meet the condition:0<lt; T< R/ 2√7. Virtual-Lab optical modeling software is applied for the simulation of designed cylindrical micro-structure, the simulation results: average transmittance rate of visible light drops 7% ,which has little impact on practical result, and we can make it up by visible wavelengths fabrication antireflection coating; 1064nm infrared laser reflection is about 75%, divergence angle is greater than 30%,which greatly reduces the single-directivity reflection echo energy of laser to achieve the purpose of laser protection.
