Teste d’une photodiode ayant un temps de mont\u00e9e inf\u00e9rieur \u00e0 15 ps. L’oscilloscope est un TEKTRONIX muni d’un sampling S4 avec un temps de mont\u00e9e inf\u00e9rieur \u00e0 25ps.<\/h3>\n

Le laser AMPLITUDE SYSTEMS model \u00a0laser \u00e0 fibre Ytterbium produit des pulses de 1ps avec une \u00e9nergie de 3nJ \u00e0 une fr\u00e9quence de r\u00e9p\u00e9tition de 40MHz ! La sortie lasers se fait sur une fibre optique 50\/125 microns coupl\u00e9 sur un t\u00e9lescope permettant d’avoir un faisceau de 4 mm de diam\u00e8tre avec une bonne coh\u00e9rence spaciale . Le r\u00e9glage de l’intensit\u00e9 d’\u00e9clairement de la photodiode se fait au moyen d’un disque \u00e0 transmitance variable. Le faisceau est r\u00e9cup\u00e9r\u00e9 sur un coupleur (lentille-fibre optique) mont\u00e9 sur le d\u00e9tecteur.<\/h3>\n

Un second oscilloscope digital LeCroy\u00a0 model …….. ayant une bande passante de 3GHz\u00a0 me permet de voir le signal avec un oscilloscope \u00ab\u00a0plus lent\u00a0\u00bb !<\/h3>\n<\/div><\/section><\/p><\/div>\n
