“…Volume Bragg Gratings (TBGs) have been widely applied in numerous advanced laser technology owing to high efficiency, angular and spectral selectivity. In the 1990s, the volume Bragg gratings recorded in different photosensitive materials was reported by many research institutions abroad, which finished the "non-focused spatial filtering" (Non-Spatial filtering) [9][10][11][12][13]. They used a divergent beam to demonstrate the angular selectivity of thick Bragg gratings.…”

Angular filtering with volume Bragg gratings in photothermorefractive glass was described. The coupled-wave theory was used to discuss the angular filtering based on Transmission Volume Bragg Gratings (TBGs). The results showed that the cutoff frequency was improved, the refractive index modulation had a greater impact on the output beam and the deviation from Bragg condition for incident beam should be less than 0.1mrad. The influence on output beam quality with TBGs parameters was analyzed. Experimental results showed that the near-field distribution of output beam through the angular filtering is better than that of the incident laser beam, and the low-frequency loss of near-field angular filtering is less than 1.8%.

We propose and perform broadband angular filtering with the combination of a volume Bragg grating and a surface grating pair. The condition for broadband operation is discussed. Near-field modulation, contrast ratio, and power spectral density are used to evaluate the filtering performances in the spatial and frequency domain. Experimental results show that the bandwidth of the output beam through the grating combination is remarkably increased, and the medium and high frequencies are effectively eliminated.
