Abstract

A white light source has a light emission device, in particular an IR laser diode, whose emitted radiation beam is converted, in a nonlinear-optical element and a conversion element, into a radiation beam with wavelengths λ1, . . . λn which can be perceived as white light and can have a higher power rating.
