Ar-Ion laser line mirrors have a specialized coating that provides a high reflectance over wavelength ranges coincident with the emission of an Ar-Ion laser. The coating has a high damage threshold suitable for use with the output beam from large-frame high-powered CW (continuous wave) Ar-Ion lasers.
