Abstract

The French Megajoule Project requires polarizers with high laser-induced damage thresholds. Such polarizers must be deposited on silica substrates, which are commonly prone to stress leading to early failure. Better stress control in the films require an optimization of the stack design as well as the deposition parameters. The thermal e-beam technique is used. We present the spectral behavior of such 1.03 micrometers polarizers in air and under vacuum at the Brewster incidence angle of 55 degrees 4 along with the damage test results.
