Abstract
We demonstrate multi-beam structured nonlinear optics in a monolayer van der Waals crystal, realizing the independent manipulation of the wavelength and topological charge of a vortex beam through second- and third-order nonlinearities. Our results pave the way for a new route to realize nanoscale tunable sources of vortex light.
