DEVICE AND METHOD FOR THE CHARACTERIZATION OF ULTRACORT PULSES
ES2724110
Method for characterizing an ultra-short pulse, comprising: delivering a reference pulse of known duration to a first detector with a prohibited band less than the photon energy of the pulse to be characterized and to a second detector with a prohibited band greater than energy per photon of the pulse to be characterized and less than twice the energy per photon of the pulse to be characterized: obtain in said first detector a monophotonic signal of reference Storef proportional to the duration of the reference pulse: obtaining in said second detector a biphotonic reference signalberef proportional to the duration of the reference pulse; send the detectors an ultra-short pulse to characterize; obtaining in said first detector a monophotonic signal Sto proportional to the duration of the ultra-short pulse to be characterized; obtaining in said second detector a biphotonic signal Sbe proportional to the duration of the ultra-short pulse to be characterized; obtaining the duration of the pulse to be characterized from said monophotonic signals, said biphotonic signals and the known duration of the reference pulse. Device for the characterization of an ultrashort pulse. (Machine-translation by Google Translate, not legally binding)
Método y dispositivo electrónico basado en un sistema de detección dual destinado a la determinación de la duración de pulsos láser ultracortos. Presenta importantes ventajas frente al resto de soluciones en aquellos casos en los que no se requiere una información detallada del perfil de intensidad y la fase: proporciona la información en tiempo real, resulta mas barato que cualquier otra técnica, más compacto, su manejo es ma sencillo y no requiere conocimientos de óptica de pulsos ultracortos.
