Contribuciones al desarrollo de tecnologías de post-procesado de materiales y de sensores ópticos de nueva generación

Abstract

In this thesis study it was discussed the effect of some key laser parameters for post-processing of different types of commercially available optical fiber transparent materials with high intensity ultrashort femtosecond laser pulses. These are generated from a commercial femtosecond fiber laser chirped pulse amplifier (FLCPA). Fiber materials such as Silica (SiO2), and poly-methyl methacrylate (PMMA) are the materials of interest in this study. The material threshold(s) damage region(s) T1, T2, and T3 are obtained and defined accurately to enable material processing tasks. Eventually, based on the precise experimental material characterization database results, different especial purpose harsh environmental optical fiber sensing application devices are micro-fabricated and tested in both silica standard fibers in form of a LPG device that is stable at ultra-high temperatures up to 1000oC, as well as in polymers through micro-fabricating LPG sensor device on a commercially available polymer optical fibers for environmental measurements.
