Abstract

L'invention concerne un laser à pompage longitudinal comportant un milieu actif à base de cristal ou de verre. On utilise au moins un laser de pompage en communication optique avec une extrémité du milieu actif pour pomper le laser. Le milieu actif est composé d'un matériau siège de l'effet laser, qui est dopé à l'aide d'un ion à activité laser. Le milieu actif comporte une première zone qui se caractérise par un niveau prédéfini d'ions à activité laser. Le milieu actif comporte une deuxième zone, située entre la première zone et le laser de pompage. Cette deuxième zone se caractérise par un niveau d'ions à activité laser inférieur à celui de la première zone.
