Flexible omnidirectional reflective film for CO2 laser protection

“…Chalcogenide glasses (ChGs) are an ideal material with excellent mid-infrared transmission performance (at least in the 9-11 μm window), low cost, and stable manufacturing capabilities and are the only glassy materials that can cover the transmission window in the 3-12 μm wavelength range with more stable chemical properties, mature production processes, and lower costs than crystalline materials [21,22] . In addition, ChGs have the advantages of adjustable components and precision moulding, and the optical refractive index can be adjusted in the range of 2-4 by component control.…”

General Strategy toward Laser Single-Step Generation of Multiscale Anti-Reflection Structures by Marangoni Effect

“…Studies have shown that the subwavelength structure with moth-eye effect has advanced anti-reflection performance [15][16][17]. At present, subwavelength structures are often fabricated by the sol-gel method [18], nanoimprinting [15,17,19], electron beam lithography [20,21], laser printing [22][23][24], etc. Moreover, researchers have found that the subwavelength LIPSS (laser-induced periodic surface structures) could be induced on the material surface by adjusting the ultrafast laser polarization shape and the external atmosphere [25][26][27].…”
