Paper Abstract

In this paper, a pulse stretcher based on multilayer volume holographic gratings(MVHG) is shown. The diffraction properties of the pulse stretcher under ultrashort pulse are investigated based on the modified multilayer coupled wave theory. The spectral intensity distributions of the diffracted beam are calculated. The diffraction bandwidth, pulse duration, pulse expansion and the total diffraction efficiency of the pulse stretcher are also analyzed. The pulse broadening is accomplished by adjusting the width of the intermediate layer of a system of MVHG. The calculation results show that using this new pulse stretcher system to broaden pulse has many advantages: the efficiency of diffraction is high, the structure of stretcher is adjustable to vary the amount of temporal broadening of the light pulse, and the structure is also more compact than alternative approaches.
