We report on experimental and theoretical demonstration of an optical comb spectrum based on a combination of cascaded stimulated Raman scattering and four-wave mixing mediated by Raman-induced nonresonant Kerr-type nonlinearity. This combination ena

Ultraviolet (UV) laser sources are of great interest in a large number of applications such as spectroscopy, bio-medicine, gas detection, water and food decontamination to cite a few. Unfortunately, the covering of this range of wavelengths is tediou

We report on a compact multi-line Raman source with a spectrum spanning from 250nm to 750nm with spectral densities ranging from 0.2 to 4µW/nm between 250-300nm and 20 to 700 µW/nm for 300-350 nm.

International audience; We report on a user-friendly sub-100 fs nonlinear pulse compression platform named FastLas. The compressor is based on gas fillable inhibited-coupling fibers and can be scaled over a large parameter-space of the input pulse. O

We report on the spectral-temporal characterization of a 1.8 μm wavelength and high power picosecond pulse Raman source. It is generated via frequency conversion to the first-order Stokes of a 27 ps chirped pulse Yb-doped fiber laser inside a molecu

The dramatic progress in power-scaling of ultra-short pulse (USP) lasers and their continuous expansion use in industrial applications call for flexible and robust beam delivery systems (BDS) over several meters. Recently, a new branch of hollow-core
