Abstract

Un laser selon l'invention comporte une cellule d'interaction 20 contenant un gaz moléculaire diatomique, un guide d'ondes capillaire 22, des dispositifs dichroïques 18 et 30 pour réfléchir principalement la radiation de fréquenoe modifiée et transmettre principalement la radiation infrarouge de la source 10 afin que le guide d'ondes capillaire augmente la longueur totale d'interaction entre la radiation infrarouge de la source 10 et le gaz moléculaire diatomique pour l'emporter sur les pertes et produire une radiation à fréquence changée diffusée par stimulation de Raman à partir des transitions rotationnelles dans le gaz moléculaire diatomique.A laser according to the invention comprises an interaction cell 20 containing a diatomic molecular gas, a capillary waveguide 22, dichroic devices 18 and 30 for mainly reflecting the modified frequency radiation and mainly transmitting the infrared radiation from the source. 10 so that the capillary waveguide increases the total length of interaction between infrared radiation from source 10 and diatomic molecular gas to outweigh losses and produce frequency-changed radiation scattered by Raman stimulation from rotational transitions in diatomic molecular gas.
