Abstract
For an ultrashort pulsed beam (UPB) with different polarization states diffracted by a volume holographic grating (VHG), the effects of the bandwidth to its diffraction properties are studied. By developing the coupled wave theory of Kogelnik, the formulas of the spectral and temporal distributions of the transmission and diffraction pulse beams are analytically given, with considering the effect of the dispersion of the grating media further. Then the bandwidths of the VHG for the UPB with different polarization states are investigated. We show the changes of the spectral and temporal distributions of the transmission and diffraction pulsed beams with different ratios of the bandwidth of the UPB to the bandwidth of the VHG. Finally, the varieties of the diffraction efficiency of the VHG for the UPB with different polarization states are studied.
