Title
(EN) SEMICONDUCTOR LASER-EXCITED SOLID LASER
(FR) LASER SOLIDE EXCITE PAR UN LASER A SEMI-CONDUCTEUR
Abstract
(EN) A semiconductor laser-excited solid laser includes a solid laser medium, a semiconductor laser for exciting the solid laser medium, a polarizer for detecting the wavelength region exciting the solid laser medium of the oscillation spectrum of the semiconductor laser, an operation means such as a comparator for normalizing the area of the spectrum detected by the polarizer and operating the area where the normalized spectrum that is detected superposed on a normalized absorption spectrum related to the excitation of the solid laser medium, and a temperature control means for controlling the temperature of the semiconductor laser based on the output from the operation means.
(FR) Ce laser solide excité par un laser à semi-conducteur comprend un milieu laser solide, un laser à semi-conducteur pour exciter le milieu laser solide, un polariseur pour détecter la zone de longueur d'onde excitant le milieu laser solide du spectre d'oscillation du laser à semi-conducteur, un moyen d'exploitation, tel qu'un comparateur, pour normaliser la zone du spectre détectée par le polariseur et pour mettre en oeuvre la zone où le spectre normalisé détecté est superposé à un spectre d'absorption normalisé en rapport avec l'excitation du milieu laser solide, et un moyen de régulation thermique pour réguler la température du laser à semi-conducteur en fonction du résultat fourni par le moyen d'exploitation.
