The development of surface finishing and coating technology at 10.6 μm for polycrystalline ZnSe laser windows is presented. Optical evaluation of the coated windows shows that the 10.6-μm absorption and reflection can be held to less than 0.1% per surface. Surface finishing procedures, theoretical coating designs, and recent experimental results for antireflection coatings for ZnSe are presented.
