摘要
In this Letter,we presented a flexible omnidirectional reflective film made of polymer substrates and multiple alternating layers of two chalcogenide glasses for full-angle CO_(2) laser protection.The structure parameters of the device were simulated for theoretical prediction of best device structure.The reflector was fabricated by alternate thermal evaporation of two chalcogenide glasses with large refractive index contrast.The reflectivity was greater than 78%at 10.6μm.The flexible reflective film can provide an effective solution for full-angle CO_(2) laser protection of the moving targets,such as laser operators and mobile optical components,with potential applications for wearable laser protective clothing.
