A solid state dye laser (5) is adapted for use in a solid state dye laser assembly having a pump (2) adapted to emit light at a first frequency and intensity. The solid state dye laser (5) includes an elongated web of polymeric host material having a gain medium disposed therein, the gain medium being in a substantially solid state and doped with a fluorescent dye adapted to emit light within a predetermined spectral tuning range. The gain medium includes polymeric cholesteric liquid crystal disposed in a planar texture and frozen into a characteristic wavelength. The solid state dye laser (5) including the gain medium is adapted for convenient movement relative to the pump (2).

L'invention concerne un laser à colorant à solide (5) destiné à un ensemble laser à colorant à solide comprenant une pompe (2) destinée à émettre de la lumière à une première fréquence et à une première intensité. Le laser à colorant à solide (5) comprend une bande continue allongée de matériau hôte polymère dans lequel est disposé un milieu de gain qui est dans un état sensiblement solide et qui est dopé avec un colorant fluorescent destiné à émettre de la lumière dans une gamme de réglage spectral préalablement déterminée. Le milieu de gain comprend du cristal liquide cholestérique polymère disposé selon une texture plane et congelé pour donner une longueur d'onde caractéristique. Le laser à colorant à solide (5) comprenant le milieu de gain est destiné à être déplacé facilement par rapport à la pompe (2).
