Abstract
We employ structured light for the second-harmonic generation from subwavelength AlGaAs nanoparticles that support both electric and magnetic multipolar Mie resonances. The vectorial structure of the pump beam allows addressing selectively Mie-resonant modes and control the strength of the generated nonlinear fields. We observe experimentally the enhancement of the second-harmonic generation for the azimuthally polarized vector beams near the magnetic dipole resonance, and match our observations with the numerical decomposition of the Mie-type multipoles for the fundamental and generated second-harmonic fields.
