论文摘要
A band-stop angular filter (BSF) based on hump volume Bragg gratings (HVBGs) was proposed. The band-stop filtering in a two-stage amplifier laser system was discussed and simulated. Simulation results show that the small-scale self-focusing effect in the laser system can be effectively suppressed with the BSF due to the control of fast nonlinear growth in the specific range of spatial frequencies in laser beam. The near-field modulation of output beam from the laser system was decreased from 2.69 to 1.37 by controlling the fast nonlinear growth of the spatial frequencies ranging from 0.6 mm-1 to 1.2 mm-1 with BSF. Besides, the BSF can be used in plug-and-play scheme and has potential applications in high power laser systems.
