TLDR
It is clearly demonstrated that stimulated Brillouin scattering is directly responsible for both fast transient dynamics of the laser and reduction of the lasers' pulse width.Abstract:
We have designed and performed an experiment that permitted direct observation of Brillouin backscattering in an Yb-doped double-clad fiber laser. Fifteen Brillouin-shifted frequencies were observed for the first time to our knowledge. We clearly demonstrate that stimulated Brillouin scattering is directly responsible for both fast transient dynamics of the laser and reduction of the laser's pulse width.read more

Wavelength beam combining of ytterbium fiber lasers.
TL;DR: Wavelength beam combining of five ytterbium fiber lasers is demonstrated in a master-oscillator power-amplifier configuration at combined powers up to 6 W, which is equal to that of an individual fiber.

Self‐induced laser line sweeping in an ytterbium fiber laser with non‐resonant Fabry‐Perot cavity
TL;DR: In this paper, a self-induced laser line sweeping (SLLS) effect for CW-pumped ytterbium fiber laser (YFL) is reported, where the effect's main characteristic is ''adiabatic'' movement (seconds) of the laser line from shorter to longer wavelengths, spanning over a spectral interval as large as 7 nm.

Suppression of stimulated Brillouin scattering in optical fibers using fiber Bragg gratings.
Hojoon Lee,Govind P. Agrawal +1 more
TL;DR: It is shown numerically that 15-ns pulses with 2-kW peak power can be transmitted though a 1-m-long fiber with little energy loss using this scheme and should prove useful for double-clad fiber lasers and amplifiers.
