Watt-level polarization-maintaining Er3+: ZBLAN fiber laser tunable from 3.4 µm to 3.7 µm Open
We demonstrate a linearly polarized Er3+: ZBLAN fiber laser in the dual wavelength pumping scheme for laser emission in the 3.4-3.7 µm spectral band. The laser is based on a polarization-maintaining heavily erbium-doped ZBLAN fiber dually …

2.8-µm polarization-maintaining Er fiber laser mode-locked by a GaSb-based SESAM Open
A GaSb-based SEmiconductor Saturable Absorber Mirror (SESAM) enables continuous-wave picosecond mode-locked operation with excellent stability of a polarization-maintaining mid-infrared Er:ZBLAN fiber laser. The GaSb-based SESAM mode-locke…

μJ-level normal-dispersion fiber optical chirped-pulse parametric oscillator Open
We demonstrate the generation of broadband tunable and synchronized pulses exceeding the microjoule level using the new concept of Fiber Optical Parametric Chirped-Pulse Oscillation (FOPCPO). The oscillator is based on a collapsed-ends pho…

Self-emergence of robust solitons in a microcavity Open
In many disciplines, states that emerge in open systems far from equilibrium are determined by a few global parameters 1,2 . These states can often mimic thermodynamic equilibrium, a classic example being the oscillation threshold of a las…

Real-Time Study of Coexisting States in Laser Cavity Solitons Open
Laser cavity-solitons microcombs have been recently introduced by our team at the University of Sussex [1]. To gain insight into their dynamics, they need to be studied with an extremely high temporal resolution, as they are ultrashort pul…

Temporal cavity solitons in a laser-based microcomb: a path to a self-starting pulsed laser without saturable absorption Open
We theoretically present a design of self-starting operation of microcombs based on laser-cavity solitons in a system composed of a micro-resonator nested in and coupled to an amplifying laser cavity. We demonstrate that it is possible to …

Low Noise High-Energy Dissipative Soliton Erbium Fiber Laser for Fiber Optical Parametric Oscillator Pumping Open
We report on a mode-locked erbium-doped fiber laser delivering highly-chirped pulses with several tens of nanojoules of energy around 1560 nm and its exploitation to efficiently pump a fiber optical parametric oscillator (FOPO), thus enabl…

Métrologie ultrarapide : application aux dynamiques laser et à l'imagerie Open
This PhD work is dedicated to optical characterization in real time. Ultrafast metrology tools have thus been used to study a pulsed laser source and also for physical phenomena imaging. The implementation of a temporally well characterize…
