Title (EN) A CO-DOPED UP-CONVERSION LASER SYSTEM
(FR) SYSTÈME LASER DE CONVERSION-ÉLÉVATION CO-DOPÉ
Abstract: front page image
(EN)The invention relates to a co-doped upconversion laser system comprising a host-material, whereas the host material is made of at least one crystal material and/ or of a glass material, which features a low phonon energy, whereas said host material comprises a dopant made of Erbium (Er3+), which is pumped by laser light with a single wavelength in the infrared wavelength range, whereas said host material furthermore comprises at least one co-dopant made of Terbium (Tb3+) or Samarium (Sm3+), in order to emit laser radiation in the range of at least one visible wavelength. This system provides a co-doped upconversion laser system featuring an elimination of coulour centres, a reduced re-absorption of the laser radiation and the emission of laser light in the range of visible wavelengths.
(FR)L'invention concerne un système laser de conversion-élévation co-dopé qui comprend un matériau hôte, ledit matériau hôte étant composé d'au moins un matériau cristallin et/ou d'un matériau vitreux et présentant une faible énergie de phonons. Ledit matériau hôte comprend un dopant composé d'erbium (Er3+), qui est pompé par de la lumière laser à une longueur d'onde unique dans la plage de longueur d'onde infrarouge. Ledit matériau hôte comprend également au moins un co-dopant composé de terbium (Tb3+) ou de samarium (Sm3+), afin d'émettre un rayonnement de lumière laser dans la plage d'au moins une longueur d'onde visible. Le système de l'invention permet d'obtenir un système laser de conversion-élévation co-dopé assurant une élimination de centres colorés, une réabsorption réduite du rayonnement laser et l'émission de lumière laser dans la plage de longueurs d'ondes visibles.
