Small dimensions, continuous submillimeter lasers HCN (lambda=337μ) and DCN (lambda=195;190μ)
Description
The development of waveguide HCN lasers (337μ) for TFR plasma entailed an increase in their power density. The scaling laws show that a 0.5 meter long discharge would be able to deliver a few mW (3mW have been already extracted). At the other end of the scaling laws, the 'one Watt' laser could be shortened by using a rectangular cross section instead of the circular one. The increase in the electron density provided for new Tokamaks makes suitable the use of a DCN laser with shorter wavelength emission (190, 195μ). The optimal working conditions for this laser were determined from the scaling laws of the HCN laser

Le developpement des lasers HCN (337μ) guide d'ondes pour les plasmas TFR a permis d'augmenter leur puissance specifique. Les lois d'echelle montrent qu'une decharge de 0,5 metre pourrait delivrer quelques mW (on a pu extraire 3mW). A l'autre extremite des lois d'echelle on a pu diminuer les dimensions du laser d'un Watt en remplacant la section circulaire par une section rectangulaire. L'augmentation de la densite electronique prevue dans les nouveaux Tokamak rend souhaitable l'utilisation d'un laser DCN a longueur d'ondes plus courte (190, 195μ). Les conditions optimales de fonctionnement de ce laser ont ete determinees a partir des lois d'echelle du laser HCNFiles
