Dark pulse emission of a fiber laser

WebSep 7, 2024 · At the maximum pump power of 9.5 W, the mode-locked fiber laser generates dark rectangular-shaped pulses with duration of 571 ns, average output power of 600 mW, fundamental repetition rate of 320 kHz. Published in: IEEE Photonics Technology Letters ( Volume: 34 , Issue: 21 , 01 November 2024 ) Article #: Page (s): 1147 - 1150 WebFeb 9, 2024 · Ultrafast vortex pulses emitted at 1 μ m band are highly sought after in many fields, here we propose an all-fiber laser for achieving that. The designed laser is switchable to emit ultrafast orbital angular momentum (OAM) and cylindrical vector beams. The beam purities are calculated to be higher than 94%.
