Title
(EN) OPTIMIZED CASCADED RAMAN FIBER-BASED LASER SOURCE FOR HIGH EFFICIENCY MID-INFRARED SPECTRAL GENERATION
(FR) SOURCE LASER À FIBRE RAMAN EN CASCADE OPTIMISÉE POUR PRODUCTION SPECTRALE D'INFRAROUGES MOYENS HAUTE EFFICACITÉ
Abstract
(EN)
A laser structure is provided that includes a pulsed source producing a pulsed signal having a low spontaneous noise component to its spectral output and a pulse-shape that is optimally flat. Also, the laser structure includes one or more optical fiber structures receiving the pulsed signal and performing Raman amplification. The pulsed signal is used to excite in the one or more optical fiber structures possessing normal chromatic dispersion, which acts as a nonlinear system for efficient mid- infrared spectral generation.
(FR)
L'invention concerne une structure laser comprenant une source pulsée produisant un signal pulsé présentant un composant de bruit spontané faible à sa sortie spectrale et une forme d'impulsion aussi plate que possible. De plus, la structure laser comprend une ou plusieurs structures de fibres optiques recevant le signal pulsé et exécutant l'amplification Raman. Le signal pulsé est utilisé pour exciter la ou les structures de fibres optiques possédant une dispersion chromatique normale, il agit ainsi comme un système non linéaire pour une production spectrale d'infrarouges moyens efficace.
