Using computer aided designing and self-matching of coating system to compress the pass-band corrugation, large size film polarizer series with good qualities in a wide spectral range were developed to satisfy requirements for very high power laser. HfO2 and SiO2 were used as the material of the film. The work-angle of these multilayer film polarizers is 60° and the work-wavelength is 1053 nm. Some testing experiments and laser induced damage experiments were done to testify the optical performance and the damage thresholds of the film polarizers.
