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.
