Patent ID: 8643940

Claim:
A system for generating polychromatic light, including: a single optical pumping means capable of emitting a monochromatic or quasi-monochromatic radiation according to a pumping wavelength and a continuous or quasi-continuous mode, a light guiding means arranged to emit a polychromatic radiation according to a continuous or quasi continuous mode at an output thereof, and a coupling means for coupling between said pumping means and said guiding means, wherein said guiding means comprises a microstructured optical fiber operating in a fundamental mode a core of which is at least partially doped at a doping rate higher than 3 mol. % with a material exhibiting an intrinsic non-linear response higher than 2/W/km, and a geometry of said optical fiber and the doping rate of said core are determined so as to match the null dispersion wavelength of said optical fiber to said pumping wavelength.
