Dual wavelength, 980 nm-pumped, Er/Yb-codoped waveguidelaser inTi:LiNbO 3

The authors demonstrate the first Er/Yb codoped waveguide laser in Ti:LiNbO3. The device was fabricated on x-cut LiNbO3 with the guides parallel to the z-axis, resulting in reduced photorefractive damage and allowing 980 nm pumping. Laser operation is demonstrated at two wavelengths, in the 1 and the 1.55 µm regions, corresponding to Yb and Er transitions, respectively.
