This work concerns the development of high average power or high energy laser with diode-pumped ytterbium-doped materials. Two host matrices were studied, CALGO...

Femtosecond laser processing in transparent materials is promising owing to the accessible control of energy deposition in time and in space. In this regime, it opens...

Electronic and vibrational dynamics have been studied in noble metal nanoparticles with high sensitivity femtosecond pump-probe techniques using a Ti :Sapphire...

The ability of optical coherence tomography (OCT) to deliver tomographic images of biological tissues in vivo non-invasively and in real-time has been a growing...

Improvement of the properties of the thin films of amorphous carbon (called Diamond Like Carbon, DLC) and search for new functionalities for this type of thin films by...

We built an experimental set-up in order to generate infrared stimulated photon echoes at the femtosecond timescale. The purpose is to examine the short time...

3D laser microfabrication inside narrow gap solids like silicon will require the use of long wavelength intense pulses. This experimental study concentrates on the...

This manuscript details the transfer of an ultra-stable optical frequency reference by means of an optical link and its application to the phase-lock of a mid-infrared...

The subject of the thesis focused on the development, characterization and use of semiconductor materials, in which the free carriers have a very short lifetime...

Local refractive index changes (RIC) are the building blocks of laser-induced optical functions in bulk transparent materials, where the use of a fused silica as a...

Single-pass free-electron lasers (FELs) are currently the most promising facilities for providing light pulses with high energies (µJ to mJ) at femtosecond time scales...
