Abstract

In this work we experimentally demonstrated a wavelength-tunable fiber laser by the use of a Er:Yb double-clad fiber placed in a Fabry-Perot cavity formed by two Dichroic Mirrors (DM). We used a 976 nm wavelength pump laser. The maximal output power from this laser that we can introduce to the fiber was 20 W. We used a Diffractive Grating (DG) with 600 l/mm in our laser cavity to get wavelength tunability. The zero order reflection from the DG is the output coupler and the first order diffracted beam is reflected back into the fiber using a DM. With this configuration we can tune the wavelength from 1535 to 1567 nm by rotating a DM at a rate of 0.02 degrees/nm. With our configuration wide tunability was possible only when we used fiber lengths between 2.5 and 3.6 m. The maximal output power was 850 mW using 3.6 m of fiber length. We believe that a Q-switched extension of this source can be used in nonlinear optics applications, such as Terahertz generation.
