Abstract: A laser system includes a laser diode that, upon activation, selectively produces a continuous wave of laser light or uniformly spaced, intermittent pulses of laser light. The system further includes a laser focuser with a plurality of lenses that focus the laser light produces by the laser diode and direct the laser light to an optical resonator. The optical resonator includes a lasing medium that, when intersected by the laser light from the laser diode, produces a beam of laser light with a wavelength that may be used for therapeutic treatment. The system is operable to produce the therapeutic laser light when the laser diode is operating in either the continuous wave mode or the pulsed mode, without moving components of the system relative to one another.

Abstract: A quasi-monolithic solid-state laser in which the optical components of the laser cavity are bonded to a common substrate via mounts. The optical components and their mounts are fixedly connected to each other and to the substrate by bonding. While the gain medium is bonded to a mount made of a different material with high thermal conductivity for heat sinking, the cavity's lens and mirror components and their mounts are all made of the same material as the substrate, or a different material that is thermally matched to the substrate, and fixedly mounted on the substrate solely with bonding. The bonding is achieved with adhesive bonding, or some other form of bonding such as molecular bonding, chemically activated direct bonding or hydroxide catalysis bonding.

Abstract: Elément (100) d'un système optique comportant: -une première enceinte(110),destinée à recevoir en circulation un fluide fonctionnel (120); et -au moins une fenêtre d'entrée et/ou sortie(140A; 140B),située sur la première enceinte et apte à laisser passer un faisceau lumineux (131). La fenêtre d'entrée et/ou sortie (140A; 140B) comporte deux hublots(142A, 141A; 42B, 141B) qui délimitent une cavité intercalaire (143A; 143B), adjacente à la première enceinte. La cavité intercalaire(143A; 143B) est destinée à recevoir un second fluide, d'indice optique prédéterminé, et est munie d'un dispositif d'ajustement de la pression en son sein (160A; 160B). L'invention permet de limiter une dégradation de faisceau lors de la traversée de la fenêtre d'entrée et/ou sortie (140A; 140B), par un choix judicieux de l'indice optique du second fluide et la pression dans la cavité intercalaire (143A; 143B). Elle trouve des applications particulièrement avantageuses dans le domaine des systèmes d'amplification laser.
