Simple design for high energy femtosecond tapered double clad fiber amplifier

Autor: Alain Mugnier, Khmaies Guesmi, Guillaume Canat, Céline Canal, Patrick Maine

Publikováno v: Fiber Lasers XVIII: Technology and Systems.

We report on a simple and robust all-fiber femtosecond MOPA system based on an optimized active tapered double-clad fiber (T-DCF). The main feature of this active medium is that the thin part, acting as a pre-amplifier, allows to propagate mostly the

CW PM Multiwatts Yb-Doped Fiber Laser Directly Emitting at Long Wavelength

Autor: Alain Mugnier, E. Goyat, David Pureur, Mathieu Jacquemet, G. Le Corre

Publikováno v: IEEE Journal of Selected Topics in Quantum Electronics. 15:120-128

We study the impact of standard active double-clad (DC) fiber characteristics and laser architectures on the generation of long-wavelength Yb-doped high-power fiber lasers around 1154 nm. Both theoretical and experimental works have been performed hi

Publikováno v: SPIE Proceedings.

Many sensing applications would benefit of multiplexing a maximum number of Distributed FeedBack Fiber Lasers (DFB FLs) on the same optical fiber. However, in such configurations, some physical mechanisms may impact DFB FLs stable operation, limiting
