Volume holographic gratings (VHG) are of wide interest in many applications because of their properties of high diffraction efficiency, excellent wavelength selectivity and angular selectivity. Recently, the potential application of VHG for manipulating laser pulses to achieve functional waveforms with large bandwidth that can be used for a variety of applications has attracted a significant amount of attention because of the flexibility and the possibility of using VHG to implement dynamic processing. However, these studies have dealt with the properties due to a single VHG rather than with a class of novel diffraction elements - multiple-layer volume holographic gratings (MVHG). In this paper, we extend the coupled wave theory of multi-layer gratings to study the Bragg diffraction properties of ULP, and present a systematically theoretical analysis on the spectrum distribution of the diffracted intensities, the diffraction bandwidth, and the total diffraction efficiency of a system of MVHG. The analysis and observations of this paper will be valuable for the accurate analysis of the interaction of ultrashort optical pulses and a variety of periodic structures, facilitating the design and the investigation of novel optical devices based on multiple layers of VHG.
