Abstract:Flat-top beams can eliminate the adverse effects of traditional Gaussian beams due to an uneven energy distribution. It is widely used in laser processing, image processing, and biomedical fields. The generation of pulsed flat-top beams using fiber lasers has gradually become a hot research topic in recent years. In this work, we propose an effective strategy to directly generate ultrafast flat-top beams with an all-fiber multimode laser without additional beam shaping. Utilizing the inherent characteristics o… Show more
