Device for Production of a Polychromatic Light over a Continuous Spectrum by Excitation at One Wavelength

摘要

A device for producing a polychromatic light including an optical pump that delivers a first radiation at a first wavelength; a light guide; and a selective injector that injects the radiation into the guide, the guide being arranged to generate a harmonic corresponding to the selected injector and provide a polychromatic light at an outlet, by non-linear excitation of the first radiation and the harmonic.
