摘要:Orbital angular momentum of photons is a subject attracting much interest over the recent few decades. Photons carry the orbital angular momentum can generate the optical vortex. Here, we demonstrate the direct generation of optical vortex pulses with stable energy and changeable orbital angular momentum at the wavelength of 1.08 and 1.3 μm. Single Laguerre-Gaussian (LG0,l) laser modes were directly generated with a laser diode as the pump source. Using Cr:YAG and graphene as the Q-switcher, the optical vortex pulses were generated. We believe that these directly generated optical vortex pulses should find promising applications in various fields, including material processing, controllable specificity of chiral matter, nonlinear frequency conversion, high-energy physics, investigation of the interaction of orbital angular momentum of photons with excitons, etc.© OSA 2014.
