DEVICE FOR PRODUCTION OF A POLYCHROMATIC LIGHT OVER A CONTINUOUS SPECTRUM BY EXCITATION AT ONE WAVELENGTH

摘要

The invention relates to a device for production of a polychromatic light, comprising optical pumping means and light guidance means. The optical pumping means are embodied to provide a first radiation at a first wavelength, characterised in comprising a selective injection means to inject said radiation into the guidance means, said guidance means being embodied to generate a harmonic corresponding to said selective injection and to provide a polychromatic light at an outlet by non-linear excitation of said first radiation and said harmonic.
