Abstract

High-order harmonics were generated from mono- and polycrystaline molybdenum disulfide (MoS₂) monolayers with an infrared femtosecond pulse. We control the Orbital Angular Momentum (OAM) and spatial polarization distribution of the generation beam by using a liquid crystal Q-plate. We then measure the OAM and the full polarization map of the emitted harmonics. We observe that monocrystaline MoS₂ behaves as a polarization converter, while polycrystaline MoS₂ may be used as a phase mask.
