Title
(EN) PULSED CASCADED RAMAN LASER

Abstract
(EN)
A pulsed cascaded Raman laser (10) includes a pulsed light source (102) for generating a pulsed light (104) having an optical spectrum centered at a source wavelength. A non-linear Raman conversion fiber (106) is coupled to the pulsed light source (102). The pulsed light (104) traverses the nonlinear Raman conversion fiber (106) and the source power at the source wavelength is converted to a power output of an output signal (108) having an output wavelength longer than the source wavelength by a cascaded Stimulated Raman Scattering process, such that most of the source power is converted to the power of the last Stokes order in a single pass through the non-linear Raman conversion fiber (106).

L'invention concerne un laser Raman pulsé en cascade (10) comprenant une source de lumière pulsée (102) destiné à générer une lumière pulsée (104) ayant un spectre optique centré sur une longueur d'onde source. Une fibre de conversion Raman non linéaire (106) est couplée à la source de lumière pulsée (102). La lumière pulsée (104) traverse la fibre de conversion Raman non linéaire (106) et la puissance de source à la longueur d'onde de source est convertie en une sortie de puissance d'un signal de sortie (108) ayant une longueur d'onde de sortie plus longue que la longueur d'onde de source par un processus de diffusion Raman stimulé en cascade, de telle sorte que la plus grande partie de la puissance de source est convertie en puissance du dernier ordre Stokes en une seule passe à travers la fibre de conversion Raman non linéaire (106).
