PHASE-CONJUGATION LASER MIRROR WITH FOUR-WAVE MIXING

摘要

Laser with a phase-conjugate mirror by a four-wave interaction in its amplifying medium (2), in which the said mirror (9) is generated by exclusively passive means (5-8). A single amplifying medium (2) is provided in a Fabry-Pérot cavity and the said passive means (5-8) are designed to generate pumping beams forming a standing wave in the said cavity. ;The laser is well suited to the machining of materials.
