Colloidal silica coatings for KrF and Nd:glass laser applications.

In this paper we discuss the performance of colloidal silica antireflection coatings which have been developed for use in high-power KrF and Nd:glass lasers. These coatings have reproducibly given transmissions of more than 99.8% per surface and have exhibited laser damage thresholds as high as 20 J/cm(2)for l-ns pulses at 1.
