Abstract
In this paper, we report on a CW 980 nm double clad photonic crystal fiber laser pumped by the CW 915 nm diode laser. The photonic crystal fiber used in the experiment has a core diameter of 40 μm, inner clad of 200 μm, an absorption coefficient of about 3 dB/m at 915 nm. The fiber length is 40 cm. In the single-end output experiment, an output power of 1.2 W with a slope efficiency of 15% has been achieved. To the best of our knowledge, it was the first time for the 980 nm Yb-doped fiber laser by using the flexile large-mode-area double-clad photonic crystal fiber.
