Patent

CA 2419974

The invention is directed to a compact optically side-pumped solid-state laser with an optimized overlap between the mode of the laser beam propagating in the laser material and the pump beam. Using a common pump volume, the compact solid-state laser can simultaneously emit laser beams at different wavelengths. The laser can be combined with nonlinear optical elements to provide a RGB three color laser architecture suitable for color projection display applications.

L'invention concerne un laser à solide, pompé latéralement de manière optique, compact, comportant un chevauchement optimisé entre le mode du faisceau laser se propageant dans le matériau laser, et le faisceau pompé. A l'aide d'un volume de pompage commun, ce laser à solide, compact, peut émettre simultanément des faisceaux laser, à des longueurs d'ondes différentes. Il est possible de combiner ce laser à des éléments optiques non linéaires, de manière à constituer une architecture de laser tricolore (rouge, vert, bleu), appropriée à des applications d'affichage de projection en couleur.
