Paper Abstract

A 2.5W superfluorescent fiber source (SFS) and a tunable PCF laser with 74.4 nm tuning range and 5.5 W output power are experimentally demonstrated by utilizing an ytterbium-doped photonic crystal fiber (PCF) as the gain medium. The tunable operation of the laser is realized by rotating a diffraction grating. Effects of the degrees of the cleaved angle at the anti-reflection fiber end on the output characteristics of the laser and the SFS are investigated. A large cleaved angle is beneficial to realize a broad laser tuning range and beneficial to obtain a high power superfluorescent fiber source without parasitic lasing.
