英文摘要:
Thin-film polarizers are essential components of large laser systems, switching the beam out of the primary laser cavity and/or protecting the system from back-reflected light. The requirements for a polarizer include specific spectral performance, high laser-induced damage resistance and low surface figure deformation. Generally speaking, a polarizer coating has a thicker thickness than a mirror coating, and a narrower bandwidth that fulfills the specific spectral specification, which makes the design and fabrication of polarizer coating challenging. Large aperture (up to similar to 900 mm in diameter) polarizer coating deposited on both BK7 and fused silica substrates with p-polarized transmittance higher than 98%, s-polarized reflectance higher than 99% at 1053 nm, and can tolerance a fluence higher than 17 J/cm(2) (9 ns) at 1053 nm has been achieved.
