In this paper, the band-stop angular filtering is performed and characterized. The band-stop angular filtering is demonstrated with a YLF laser with the wavelength of 1053 nm. The TBGs used in the experiment has the angular selectivity of 1.35mrad, the period of 1.97μm and the diffraction efficiencies of about 92%. Since part of the characteristic spatial frequencies was cleared out with the band-stop angular filter, there was an intensity drop on the edge of the filtered beam. The optical axis for the incident and output beams keeps basically coaxial after filtering, which can be used as a plug-and-play device in the high-power laser systems. The characteristic spatial frequency of 1.98mm-1 corresponds to the TBG deviation angle of 1.35mrad, and the spatial frequencies around the characteristic frequency of 1.98mm-1 were reduced to 20% compared to that of the original beam. The desired bands in the laser beam can be filtered with different TBGs, which has potential applications in high power lasers.
