  • Pumped laser and optimized lasing medium
    Patent number: 6961360
    Abstract: A longitudinally pumped laser including one or more active lasing media arranged in an optical laser cavity and at least one pumping device emitting at least one pumping beam toward the at least one active lasing medium. The pumped beam or beams is coupled with the active medium. At least one of the active lasing media includes one or more non-homogeneously doped zones, and the dimension of the doped zones and/or the distribution of the dopants is chosen on the basis of the desired transverse mode of the laser cavity. Such a laser can be used as an amplifier.

  • Pumped laser and optimised lasing medium
    Publication number: 20020122448
    Abstract: Longitudinally pumped laser comprising one or more active lasing media arranged in an optical cavity and at least one pumping means (4) emitting at least one pumping beam toward the active lasing medium or media (3), means (5) for the coupling of the pumped beam or beams with the active medium, characterized in that at least one of the active lasing media comprises one or more non-homogeneously doped zones (8) and in that the dimension of said doped zones (8) and/or the distribution of the dopants is chosen on the basis of the desired transverse mode of the laser cavity.
