Improved PbF Coatings for the Infrared

Source

A technique is described for reproducibly depositing single layer PbF2 antireflection coatings for CdSe that have a damage threshold of about 50 MW/cm2 for 2.87 μm laser radiation. This is an 8-fold increase in damage resistance over coatings made by other methods. These same coatings applied to Ge have a damage threshold of about 22 MW/cm2. The coated Ge value is less probably due to the index mismatch between the PbF2 and the Ge.
