Cet autocorr\u00e9lateur de troisi\u00e8me ordre \u00e0 contraste ultra \u00e9lev\u00e9 permet de caract\u00e9riser l\u2019impulsion laser ou de voir les plus petites r\u00e9pliques pr\u00e9 et post-impulsion des lasers les plus puissants. \nSource\u00a0: UltraFast Innovations<\/figcaption><\/figure>\n<\/div>\n\n\n

Distribu\u00e9 en France par Opton Laser International, le fabricant allemand UltraFast Innovations propose un autocorr\u00e9lateur de troisi\u00e8me ordre \u00e0 contraste ultra \u00e9lev\u00e9. Baptis\u00e9 Tundra, cet outil de diagnostic est tr\u00e8s sensible et adapt\u00e9 \u00e0 la mesure du contraste des impulsions laser. La plage dynamique atteint jusqu’\u00e0 14 ordres de magnitude et permet la caract\u00e9risation de l\u2019impulsion laser. L\u2019utilisateur voit les plus petites r\u00e9pliques pr\u00e9 et post-impulsion des lasers les plus puissants du march\u00e9. L’autocorr\u00e9lateur utilise des composants r\u00e9fl\u00e9chissants (hormis les cristaux non lin\u00e9aires g\u00e9n\u00e9rateurs de signaux) et garantissant des traces de corr\u00e9lation exemptes d\u2019artefacts de mesure. L\u2019interface logicielle conviviale facilite la mise en \u0153uvre des contr\u00f4les et permet ainsi de comparer plusieurs mesures et de les analyser. Le logiciel simule l\u2019\u00e9paisseur des \u00e9l\u00e9ments optiques g\u00e9n\u00e9rant une r\u00e9plique d\u2019impulsion. La r\u00e9solution peut \u00eatre r\u00e9gl\u00e9e tout au long de la mesure pour minimiser le temps d’acquisition. Le dispositif est utilis\u00e9 dans une large gamme d’applications n\u00e9cessitant une compr\u00e9hension approfondie du contraste des impulsions et les possibles structures d’impulsions parasites. Contrairement aux autocorr\u00e9lateurs de second ordre, les pr\u00e9 et post-impulsions peuvent \u00eatre distingu\u00e9es en raison de la nature de troisi\u00e8me harmonique du signal. Automatis\u00e9, l\u2019outil est indispensable pour la caract\u00e9risation d’impulsions laser ultracourtes et intenses. <\/p>\n\n\n\n
