Abstract
An active element slab for a laser source is presented. The active element slab includes at least one input surface of a pump beam, a first section in the shape of an elongated bar along a longitudinal axis that includes a first doped matrix configured to absorb the beam pump to amplify a laser beam travelling longitudinally, a second section that covers at least partially the first section, the second section that includes a second doped matrix configured to absorb the laser beam and of being transparent to the pump beam.
