Abstract
In this contribution, we report on an 80-μm core diameter Yb-doped rod type photonic crystal fiber laser emitting up to 94W in CW regime when operating at 977nm, which is to our knowledge the highest output power ever achieved from a single-mode solid-state laser operating at this wavelength. Key parameters of ytterbium doped 3-level laser, such as transparency pump intensity, pump absorption saturation, and gain competition between three and four level laser operation are then discussed in the particular context of high power fiber laser operating at 977nm. Possible applications of the demonstrated source are then discussed.
