Title
(EN) MODE LOCKED PULSED DYE LASER
(FR) LASER COLORANT PULSE A MODE BLOQUE
Abstract
(EN) Apparatus using dye lasers for the production of pulsed light at a desired wavelength wherein the dye cells (4, 5) are fed with a weak beam of a narrow desired wavelength and pumped at another wavelength, thus producing an amplified output at the desired wavelength, the apparatus having a special aptitude in certain medical treatments. A metal vapour laser is employed using copper and gold active media in spatially separated regions, with the strong copper output at 511 nm and 578 nm being passed through a wavelength selective mirror (1) to pump two dye cells (4, 5) which are locked to the weaker 628 nm output obtained from the gold vapour discharge.
(FR) Dans un appareil utilisant des lasers colorants pour la production de lumière pulsée à une longueur d'onde désirée, les cellules colorantes (4, 5) sont acheminées à l'aide d'un faisceau faible de longueur d'onde désirée étroite et pompées à une autre longueur d'onde, produisant ainsi une sortie amplifiée à la longueur d'onde désirée, l'appareil pouvant spécialement être utilisé dans certains traitements médicaux. On se sert d'un laser à vapeur métallique utilisant des supports actifs de cuivre et d'or dans des régions spatialement séparées, la sortie de cuivre la plus forte de 511 nm et de 578 nm traversant un miroir sélecteur de longueur d'onde (1) destiné à pomper deux cellules colorantes (4, 5) bloquées à la sortie la plus faible de 628 nm obtenue à partir de la décharge de vapeur d'or.
