In this study, we performed LBO-OPO with an extended cavity configuration. Resulting vortex idler output was obtained in the wavelength range of 1150-1892nm. A maximum idler vortex output energy of 1.1 mJ was achieved. This system enables us to transfer selectively a topological charge of the pump beam to the idler outputs.
Such broadly tunable optical vortex lasers have been potentially applied in a variety of fields, including chiral nanostructures fabrication.
