Abstract
L'invention concerne un dispositif laser ainsi que des applications, comprenant un laser à cascade quantique et un générateur d'impulsions pour le fonctionnement pulsé du laser à cascade quantique. Le dispositif laser selon l'invention est caractérisé en ce que le laser à cascade quantique peut fonctionner, grâce au générateur d'impulsions, avec des paquets d'impulsions couplés à des fréquences comprises dans la plage de 1 Hz à 100 kHz et en ce qu'un dispositif d'évacuation de chaleur est relié au laser à cascade quantique. On peut utiliser des lasers Fabry-Pérot à faible coût comme lasers à cascade quantique. Grâce à un procédé de commande spécial, on peut obtenir une émission partiellement cohérente, de type diode électroluminescente.
