Diode\u00a0<\/b><\/i><\/span><\/span><\/strong>GaAs 976nm monomode doubl\u00e9e en fr\u00e9quence dans un PPLN<\/b><\/i><\/span><\/span><\/strong><\/p>\n

Cette unit\u00e9 FITEL HPU50211 se compose d’une diode GaAs coupl\u00e9e sur une fibre monomode.
\nLa diode laser se compose d’un miroir de sortie ext\u00e9rieur \u00e0 celle-ci.
\nLa puissance de sortie est de 500mW@976nm et \u00e0 0.6A
\nCette puissance est inject\u00e9e dans un doubleur de fr\u00e9quence se composant d’un
\ncristal PPLN (Periodically Poled Lithium Niobate) qui est un cristal a effet non lineaire permettant de convertir avec un rendement sup\u00e9rieur \u00e0 85% dans le bleu \u00e0 488nm!<\/span><\/span><\/strong><\/p>\n

Les cristaux PPLN (Periodically Poled Lithium Niobate)<\/strong> repr\u00e9sentent probablement la plus grande avanc\u00e9e dans le domaine du doublage de fr\u00e9quence depuis l’apparition des cristaux BBO et LBO. Ils permettent d’obtenir des rendements de conversion tr\u00e8s \u00e9lev\u00e9s avec des lasers de puissance relativement modeste, notamment les diodes laser fibr\u00e9es comme votre module FITEL \u00e0 976 nm.<\/p>\n<\/div><\/section><\/div>\n
