Paper Abstract

A few holographic silver gratings with maximum diffraction efficiency in the 700-1100nm wavelength range were designed. They can be attractive for stretching and compressing pulse in CPA (chirped pulse amplification) technique. KPP1206 photoresist was used to model the final pattern on photoresist thin film. This paper was devoted to consider super Gaussian gratings. Therefore, approximately identical exposure energy density intervals were used for optimizing grating profile. Accordingly, the Genetic Algorithm (GA) was employed by Grating Solver software to optimize groove spacing, groove depth and groove shape of the grating for TM polarized light in the 1st order (littrow mount).Also, Dependency of diffraction efficiency (DE) to depth and duty cycle of super Gaussian silver gratings in 1064nm was shown.
