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.

An active element slab for a laser source, comprising:
- 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 pump beam to amplify a laser beam travelling longitudinally;
- a second section that covers, at least partially, the first section, where the second section includes a second doped matrix that is configured to absorb the laser beam and is transparent to the pump beam;
- and
- a third section in the shape of an elongated bar along the longitudinal axis, which includes a third doped matrix that is configured to absorb parasitic laser beam, the first section including two parts between which the third section is sandwiched.
