A beam delivery system (BDS) fibered with hollow core photonic crystal fibre (HC-PCF) has been identified as very promising for ultra-short pulse (USP) laser micromachining for it allows flexible, secured and robust laser beam delivery to the work pi

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.

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 development of the Raman gas-filled hollow core photonic crystal fibers allow to exacerbate the light-matter interaction with extremely high efficiency. Among the nonlinear optical effect that were extensively explored we count stimulated Raman s
