Génération de supercontinuum dans l'infrarouge moyen à partir de fibres optiques à saut d'indice
|Advisor:||Bernier, Martin; Vallée, Réal|
|Abstract:||This thesis focuses on the generation of supercontinuum (SC) in the mid-infrared (mid- IR) from step-index optical fiber in order to help the next generation of spectroscopic laser systems in both remote sensing and micro-spectroscopy applications. A comprehensive review of the literature as well as an explanation of the theoretical basis of mid-IR SC generation is presented. Two impact results were obtained during the master. First, the first cascaded SC up to 8 μm was demonstrated via a single-mode AsSe optical fiber by pumping with amplified picosecond pulses. Then, the first SC reaching an average power in the watt-level was demonstrated in an AsSe fiber, thanks to the amplified femtosecond fiber laser emitting high energy pulses at 3.6 μm and the deposition of a Al2O3 anti-reflection coatings.|
