In this article, the transfer characteristics of the deformable medium film valve with sinusoidal form phase grating and with sawtooth form phase grating are discussed and conmpared.

Laser-induced damage thresholds of multi-layer dielectric mirrors and multi-layer dielectric gratings were investigated in this paper.

First, choose suitable angle of total reflection, then evaporate the optical medium film on the total reflection interface to compensate phase retardation, which can not only improve the stability but also improve the achromatism.

Diffraction property of multi-layer dielectric gratings studied by rigorous coupled-wave analysis;
