摘要: 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 an 80 microm diameter rod-type emitting up to 94 W in continuous wave regime when at 977 nm, which is our knowledge highest output ever achieved from a single-mode solid-state wavelength. Key parameters three-level laser, such as transparency pump intensity, absorption saturation, and gain competition between three four-level operation are then discussed particular context high nm.
