In this paper, we investigate power scalability of ytterbium-doped ultra large core photonic crystal fiber laser operating on the zero-line transition. We first report on an 80 microm core diameter… (More)
We demonstrate a Single-Mode (SM) Large-Mode-Area (LMA) ytterbium-doped PCF rod fiber laser with stable and close to diffraction limited beam quality with 110W output power.… (More)
Several industrial applications require highly reliable and efficient laser systems delivering high average power in the modelocking regime. For this purpose, the frequency feedback laser… (More)
We report on a picosecond laser system that can run from single shot to 50MHz, with energies up to 100µJ.
This paper presents accurate modeling and experimental results concerning a self-starting ring cavity laser whose pulse duration can be changed from the fs to the ps regime. This laser delivers more… (More)
We have designed an ytterbium rod-type fiber laser oscillator with tunable pulse duration. This system that delivers more than 10 W of average power is self mode-locked. It yields femtosecond to… (More)
We report on 83W, 14μJ, 5.9MHz, 30ps MOPA fiber laser based on an Yb modelocked fiber oscillator and a rod-type LMA amplifier. By frequency tripling, this configuration can generate up to 20W of UV.
We demonstrate high-frequency Q-switching of a fiber rod laser with a Single-Crystal Photo-Elastic Modulator (SCPEM) made of a LiTaO₃₋ crystal. This type of photo-elastic modulator can be driven… (More)
High power harmonic generation of visible (green) and UV light have been dominated mainly by solid-state lasers but, in recent years, fiber laser based systems have started to challenge them . In… (More)
We study the limitation in energy storage of LMA Yb-doped fibers and show the importance of the gain recovery time for high power nanosecond laser and amplifier design.
