Summary
[edit]DescriptionTiSa laser.jpg |
Français : Laser Titane Saphir en fonctionnement. Le laser de pompe vert sert à créer une inversion de population dans le cristal, qui est un milieu amplificateur à 4 niveaux émettant dans l'infrarouge (~800nm). Ce laser de KMLabs génère un train d'impulsions de <20fs, à un taux de répétition de 80MHz, pour une puissance moyenne de 430mW avec un laser de pompe Millennia 5W. Un gros plan du cristal est disponible, voir Image:TiSa crystal.jpg. English : Titanium-Sapphire laser in use. The green pump laser creates a population inversion in the crystal, wich is a 4-level amplifying medium emitting in the near infrared (~800nm). This KMLabs oscillator generates pulses of <20fs duration, at a 80MHz repetition rate, for an average power of 430mW with a 5W Millennia pump laser. A close-up of the crystal is available, see Image:TiSa crystal.jpg. |
