Melik-Gaykazyan, Elizaveta; Koshelev, Kirill; Choi, Jae-Hyuck; Kruk, Sergey; Park, Hong-Gyu; Fedyanin, Andrey; Kivshar, Yuri


We employ doughnut-shaped cylindrical vector beams to observe the enhanced second-harmonic generation from individual subwavelength AlGaAs nanoparticles which support both electric and magnetic multipolar Mie-type resonances at the fundamental and double frequencies.
