In order to study diffraction characteristics of longitudinal chirped volume Bragg gratings, transfer matrix algorithm was used. Effects of the thickness, refractive index modulation and chirped wavelength range on the central diffraction efficiency of the longitudinal chirped volume Bragg gratings were calculated. The results show that central diffraction efficiency increases with the increase of the thickness and the refractive index modulation of the Bragg grating. However, with the increase of the chirped wavelength range, the central diffraction efficiency decreases. The research results have certain reference value for design and manufacture of large size of chirped volume Bragg gratings.
