Patent

CA 2617857

A pulsed laser is disclosed comprising an active lasing medium (1), an output coupler (5) and a rear cavity mirror (6). The rear cavity mirror (6) is attached to a mount (21) via an intermediate attachment (15). Heating elements are embedded within the attachment (15). The attachment (15) is heated in order to vary the physical length of the laser cavity in a manner which seeks to stabilise the output energy and wavelength of the laser pulses emitted from the laser cavity.

L'invention concerne un laser pulsé constitué d'un matériau actif (1), d'un coupleur de sortie (5) et d'un miroir de cavité arrière (6). Ce miroir de cavité arrière (6) est fixé à un support (21) au moyen d'une fixation intermédiaire (15). Des éléments chauffants sont incorporés dans cette fixation (15). Ladite fixation (15) est chauffée afin de faire varier la longueur physique de la cavité laser d'une manière visant à stabiliser l'énergie de sortie et la longueur d'onde des impulsions laser émises par la cavité laser.
