Abstract: A laser system having a cavity formed by at least two sub-cavities and a mechanism for optically pumping a first of the at least two sub-cavities. In the system, the optical pumping mechanism is arranged in such away to not reach a laser emission threshold of the first sub-cavity, the first sub-cavity (2) comprising a device for generating a short pulse, a second sub-cavity (3) comprising an external triggering device. The first and second sub-cavities are coupled such that the triggering of the second sub-cavity has at least two such laser systems, to a light emission system with a wide spectral band, comprising such a laser system and a mechanism for generating non-linear optical effects inserted into the second sub-cavity, and to a light generator with a wide spectral band, comprising such a laser generator having at least one laser system provided with a mechanism for generating non-linear optical effects inserted into the second sub-cavity.

Abstract: 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.
