    Based on the Kogelnik′s coupled-wave theory and transfer matrix method, the expressions of temporal and spectral diffracted field and intensity are deduced, while a femtosecond pulse incidents on a transmitted stratified volume holographic grating (SVHG). Simulation results show that, each VHG layer diffracts out a sub-pulse and the waveform of which is modulated by corresponding VHG layer and and buffer layers parameters. The buffer layers placed on VHG′s right side will translate the diffracted sub-pulses along the negative time-axis, whereas the left side will not translate peak position, such property can be used to realize modulated femtosecond pulse train by controlling VHG and buffer layers parameters. At last, an explanation on these phenomena is given based on the diffraction efficiency and expressions of diffracted spectrum.Key words
