Abstract
A wide-spectrum compact ultrabrief laser source includes a rare-earth ion primary laser. The source is pumped by a pump light flux centered on a wavelength λ, the flux being emitted by a solid laser pump source. The primary source emits a primary light flux centered on a wavelength λof spectral width Δλ. The latter is injected via an optical injection into a photonic crystal fiber having a length L, a cross-section d, and a set of cavities of diameter φ. A coupling optics collects the light flux at the output of the photonic crystal fiber. The light flux is centered on a wavelength λand has a spectral width Δλ. The spectrum is subjected in the photonic crystal fiber to an enlargement which is due for more than 50% to phase self-modulation.
