Frequency tuning and doubling in Yb-doped fiber lasers
- 105 Downloads
A compact Yb-doped fiber laser (YDFL) based on a tunable fiber Bragg grating (FBG) with ∼6 W output power and ∼45 nm tuning around 1080 nm has been developed. The laser output power and its spectral width (∼0.15 nm) do not change significantly at the tuning, while the FBG reflection coefficient increases with an increase in FBG compression. It has been shown that this increase is due to stress-induced changes in the FBG’s refractive-index modulation amplitude. Intracavity frequency doubling in the YDFL has also been performed. About 0.4 W of green radiation with tuning in the range 540–548 nm has been achieved with a KTP nonlinear crystal.
