A laser system includes an apparatus and method having a primary laser resonator having a laser medium therein for producing a laser beam of a first wavelength and a second laser resonator optically connected to the primary resonator to allow a portion of the laser energy from the primary laser resonator to pass into the secondary laser resonator. An optical parametric oscillator is located intracavity of the secondary laser resonator and includes a non-linear crystal for producing a laser beam of a second wavelength therefrom. The dual resonators combine a secondary laser cavity and an optical parametric oscillator to produce a predetermined output wavelength. The compact multiple resonator laser system has a substrate mirror system having four mirror surfaces thereon positioned to form two laser resonators. A multi-pass corner cube is mounted to fold the light beams between a pair of substrate mirrored surfaces while a transfer corner cube is positioned to transfer a laser beam from one resonator to the second resonator to form a very compact pair of laser resonators. A method of producing a coherent light beam of a predetermined output wavelength uses the compact laser system apparatus.
Système laser (10) comportant un dispositif comprenant un résonateur laser primaire (11) ayant à l'intérieur un milieu actif (12) pour produire un faisceau laser d'une première longueur d'onde et un second résonateur laser (27) relié optiquement au résonateur primaire (11) afin de permettre à une partie de l'énergie laser provenant du résonateur laser primaire (11) de passer dans le second résonateur laser (27). Un oscillateur paramétrique optique (27, 33) est situé dans l'intracavité du second résonateur laser (27) et comprend un cristal (33) non linéaire pour produire à partir de celui-ci un faisceau laser d'une seconde longueur d'onde.
