Ce laser est un prototype pour l’\u00e9valuation du laser 2kHz \u00e0 excimer muni d’une turbo soufflante pour refroidir les gaz apr\u00e8s la d\u00e9charge.
\nLe but \u00e9tait de tester les caract\u00e9ristiques de la ligne de Blumlein en BaTiO3, les caract\u00e9ristiques des \u00e9lectrodes de pr\u00e9ionisation \u00e0 effet corona ainsi que les \u00e9lectrodes de d\u00e9charge.
\nLa commutation \u00e9tait faite par un thyratron \u00e0 hydrog\u00e8ne EG&G type HY-1102. Une unit\u00e9 trigger EG&G model TM27 servait \u00e0 faire commuter le thyratron.
\nLes miroirs composant le r\u00e9sonateur sont des miroirs multidi\u00e9lectrique Rmax 99.98% et Rs 87%.
\nLe faisceau laser pr\u00e9sente une dimension \u00e0 la sortie de 9 x 2.5mm de section et une \u00e9nergie de 5 mJ \u00e0 14kV avec une dur\u00e9e d’\u00e9mission de 10 ns.<\/b><\/span><\/span><\/span><\/span><\/h3>\n<\/div><\/section><\/div>\n

Bo\u00eetier laser ouvert montrant une ligne de \u00ab\u00a0Blumlein\u00a0\u00bb en BaTiO3 avec les 2 \u00e9lectrodes de d\u00e9charge et la 2 \u00e8me ligne de \u00ab\u00a0Blumlein\u00a0\u00bb sortie du laser. Ce laser fonctionnant en KrF\u00a0 \u00e0 248 nm \u00e9met 5 mJ par pulse en 6ns jusqu’\u00e0 100pps sans circulation de gaz.<\/h4>\n<\/div><\/section><\/p><\/div>\n
