Development of 1.06 Micron High Efficiency Antireflective Coating,

Abstract

This article carries out analyses of errors associated with two layer antireflective coatings. It points out that two layer antireflective coatings associated with non lambda/4 stacks have more stable optical properties than lambda 4 stacks. Using Ta2O5 and SiO2 to act as film materials, two layer antireflective coatings were prepared on Kg glass substrate. The single surface reflectivity was below 0.03%, and laser damage threshold values were greater than 7 GW/sq cm (laser light wave length 1.06 micron, pulse width 1 ns). jg
