High-power diffraction limited sources emitting around 976 nm have many applications. To cite a few, several tens of watts at 976 nm laser is an outstanding source for high-brightness pumping of Yb-doped solid-state lasers [1]. In another context, 97

Since the two last decades, ultrashort pulses operating around 2 μm are useful for a commercial and scientific applications, e.g. mid-infrared supercontinuum generation [1] or pumping of optical parametric oscillators. To obtain such pulses, mode-lo

Frequency doubled sub 50 fs Erbium-fiber lasers are ideal tool used to seed Ti:sapphire amplifier. Therefore, over last decade large number of all-fiber laser architecture has been reported for such application. Nevertheless, the emitted pulses are u

We report on a 3 W Mid-IR supercontinuum extended up to 4.6 μm based on an all-PM thulium doped fiber gainswitched laser seeding an InF3 fiber. This innovative fiber presents a specific design that increases non-linear effects and shows very weak ba

We propose an innovative, fully space–time model to take into account the seed-dependent nature of ageing penalties in high-power ytterbium-doped fibre amplifiers. Ageing is shown to be based on the on-going competition between photo-darkening and

We propose an innovating model to describe the kinetics of competing photo-darkening and photo-bleaching phenomena in high-power, Ytterbium-Doped-Fibre-Amplifiers. This model makes use of aggregated species of trivalent Ytterbium and divalent ions, w

We report a high performance, fully monolithic 40 μm core, Yb-doped photonic crystal fiber amplifier module. The developed fused combiner allows us to couple 6 pumps of 50 W at 976 nm and 5 W of signal at 1064 nm in the PCF amplifier. We then produc

We report on a passively mode-locked fiber laser emitting around 976 nm. The laser emits chirped pulses with a duration of 1.02 ps and 12 nJ at 40,7 MHz. External compression leads to pulses as short as 286 fs.

We demonstrate an Ytterbium-doped fiber laser system generating high energy pulses at the non-conventional wavelength of 977 nm. An actively Q-switched master fiber oscillator delivers 1.2 W of average power in 12 ns pulses at 82 kHz of repetition ra
