Abstract :
A method of integral equations (IE) is applied to a simulation of diffraction efficiency (DE) of metal-dielectric and all-dielectric diffraction gratings (DG). Two factors narrowing the spectral band of laser pulse reflection into minus first space harmonics (MFSH) are analyzed. It is found that by using a chirped mirror instead of a multilayer all-dielectric one it is possible to make diffracted spectrum 20-30 nm wider.
