Abstract
We review our recent work on fiber based laser systems in the continuous wave and nanosecond pulse regime. A significant power and energy scaling was possible by applying low-numerical aperture large-mode-area ytterbium-doped double-clad fibers which emit an excellent beam quality and possess a reduced nonlinearity due to a mode field diameter of >20 μm. We report on a continuous wave fiber laser with an output power approaching 500 W from a single fiber and the amplification of ultrastable, narrow linewidth single-frequency radiation to the 100 W level with diffraction-limited beam quality without the limitation of nonlinear effects. Furthermore the amplification of nanosecond pulses to millijoule pulse energy and average powers up to 100 W is demonstrated.
