Patent

CA 2264753

The invention refers to a laser having first and second reflecting elements (3, 4) defining a laser cavity; a laser microchip (1) provided in the laser cavity to generate laser radiation of a fundamental wavelength; and a quasi- phase matching non-linear optical element (2) provided in the laser cavity to receive said laser radiation of the fundamental wavelength from the laser microchip (1) and to emit frequency doubled laser radiation (SH) of a wavelength half as long as the fundamental wavelength.

La présente invention se rapporte à un laser comportant un premier et un second éléments réfléchissants (3, 4) définissant une cavité laser; une micropuce laser (1) disposée dans la cavité laser de façon à produire un rayonnement laser de longueur d'onde fondamentale; et un élément optique (2) non linéaire assurant une quasi adaptation de phase, disposé dans la cavité laser de manière à recevoir ledit rayonnement laser de longueur d'onde fondamentale émanant de la micropuce laser (1) et à émettre un rayonnement laser à fréquence doublée (SH) d'une longueur d'onde égale à la moitié de la longueur d'onde fondamentale.
