CA 2261036

An external cavity laser system composed of a semiconductor diode laser (10), a temperature control (30) and injection current control (40) means the diode laser, an external cavity (60) with a wavelength selector and means for controlling the laser temperature (20), laser injection current and the wavelength selector (110) to obtain arbitrary frequencies within the tuning range of the laser.

La présente invention concerne un système laser à cavité externe. Ce système est constitué d'un laser à diode à semi-conducteur (10), d'un régulateur de température du laser (30), d'un régulateur de courant d'injection du laser (40), d'une cavité externe (60) à sélecteur de longueur d'ondes. L'invention concerne également, un tel régulateur de température du laser (20), un tel régulateur de courant d'injection du laser, et un tel sélecteur de longueur d'ondes (110) pour l'obtention de fréquences arbitraires dans les limites de la plage d'accord du laser.
