System for emitting a polychromatic light, provided with coupled sub-cavities

摘要

A system for emitting a polychromatic light, has a laser cavity device used to optically pump the laser cavity emit radiation according to at least one excitation wavelength and light guiding mechanism arranged in such a way as to supply a polychromatic light to an outlet in the event of excitation by the radiation in a non-linear interaction regime. In the system, the guiding mechanism is arranged inside a cavity formed by at least two sub-cavities, a first sub-cavity forming the laser cavity and a second sub-cavity comprising the guiding mechanism, the first and second sub-cavities being coupled.
