The generation of femtosecond optical vortex beams with megawatt powers directly from a fiber based Mamyshev oscillator
Numerous approaches have been developed to generate optical vortex beams carrying orbital angular momentum (OAM) over the past decades, but the direct intracavity generation of such beams with practical output powers in the femtosecond regime still remains a challenge. Here we propose and experiment...
