Paper Abstract
The wavefront characteristics in the angular filtering based on the transmitting volume Bragg gratings (VBGs) recorded in the photothermorefractive glass are discussed. The wavefront distortions were introduced in the super-Gaussian beam and the wavefront distribution of the diffracted beam was analyzed. Stimulation results show that the low frequency wavefront distribution with the period larger than 40mm is difficult to be corrected while the high frequency wavefront with period smaller than 0.1mm is easy to be corrected with VBGs. The middle-high frequency wavefront distortion with period between 5mm and 0.25mm can be effectively corrected with VBGs with the appropriate angular selectivity, and the PV values can be reduced 167 times and 1000 times than that of modulated beam, respectively.
