Study the effect of the substrate on the FWHM pulses for the chirped mirrors

Abstract

We consider the design of double chirped mirror(D.C.M) with the various substrates that fused Silica BK7, as well as appearance in current study the FWHM for the reflected pulses is reducing when the lowest levels of dispersed oscillations are achieving if the matching index of substrate with index of one of the coated material and if the double-chirping is using for chirping mirrors (CM)arrangement.
