Design of High-efficient Transmission Gratings in Fused Silica for Femtosecond Laser at a Wavelength of 1040nm

摘要：

Design and the performance of high-efficiency transmission gratings embedded in fused silica for a femtosecond laser system at a wavelength of 1040nm is described in this paper. When the density and depth of the grating are 12001ines/mm and 1.55um respectively,the -1st order diffraction efficiency in excess of 97％ for TE polarization is achieved in Littrow conditions. The redundancy of the depth of groove and duty cycle of transmission grating is analysis.
