Abstract

Laser à plusieurs longueurs d'onde et à commutation rapide. Le laser comprend un miroir de renvoi 24 orthogonal au réseau de diffraction 8, le faisceau lumineux correspondant à l'ordre zéro du réseau retraversant la roue tournante par l'un des éléments optiques. Application au dosage des polluants de l'atmosphère.
