Thin layer deposition of TiO<sub>2</sub> and PMMA on optical micro or nano fibers for nonlinear optics Open
Over the last twenty years, silica optical tapered micro or nanofibers (called ONF in the following) have been widely exploited for a large range of potential applications in several areas of research for their original properties of light…

Design of composite nanofibers for new all-solid state Raman wavelength converters Open
We present the design of composite optical nanofibers coated with different nonlinear materials (PMMA and TiO 2 ) for the realization of new all-solid state Raman wavelength converters. Two coating processes, multilayer dip-coating and ato…

Improving photon pair generation in silica nanofibers through PMMA/DR1 nonlinear coating optimization Open
We report on the use of PMMA/DR1 coating to enhance the efficiency of photon pair generation in silica nanofibers. The coating improves the second-order nonlinear susceptibility of the nanofibers, leading to improved photon pair generation…

Orbital angular momentum beams generation from 61 channels coherent beam combining femtosecond digital laser Open
We report on the use of a 61 beamlets coherent beam combination femtosecond fiber amplifiers as a digital laser source to generate high-power orbital angular momentum beams. Such an approach opens the path for higher-order non-symmetrical …

Coherent beam combining of 61 femtosecond fiber amplifiers Open
We report on the coherent beam combining of 61 femtosecond fiber chirped-pulse amplifiers in a tiled-aperture configuration along with an interferometric phase measurement technique. Relying on coherent beam recombination in the far field,…

Coherent beam combining of seven fiber chirped-pulse amplifiers using an interferometric phase measurement Open
Coherent beam combining in tiled-aperture configuration is demonstrated on seven femtosecond fiber amplifiers using an interferometric phase measurement technique. The residual phase error between two fibers is as low as λ/55 RMS and a com…

140 W peak power laser system tunable in the LWIR Open
We present a high peak power rapidly tunable laser system in the long-wave infrared comprising an external-cavity quantum cascade laser (EC-QCL) broadly tunable from 8 to 10 µm and an optical parametric amplifier (OPA) based on quasi phase…
