Systèmes lasers intégrant des micro-miroirs déformables a base de MEMS optiques

Abstract

This work deals with the integration of MEMS (Micro- Electro- Mechanical- System) in fibre laser systems in order to generate short pulses. Q-switching short laser cavities associated with these components produces pulses in the nanosecond regime. These deformable micro-mirrors reached modulation frequencies upper than one megahertz, giving access to mode-locking in fibre laser sources. This new fibre laser system showed MOEMS capability to replace more famous modulators, as acousto-optic or electro-optic ones. They offer a good potential in miniaturization and cost reduction of pulsed fibre laser sources.LIMOGES-BU Sciences (870852109) / SudocSudocFranceF
