Abstract

Laser source comprising a first active arm extending from a first end reflector up to a dispersing system grid and containing an amplifier medium that produces a first luminous beam. A second passive arm extends from the grid to a second end reflector, the grid generating a second beam by diffraction of the first beam, wherein the second end reflector closes the second passive arm and is partially reflecting to enable extraction of a luminous flux. An optical component produces, from the second beam, a third beam translated and antiparallel, to return to the grid which, by diffraction, forms a fourth beam translated and antiparallel to the first beam.
