Abstract

We demonstrate single-longitudinal-mode and wavelength-tunable operation of Er:Y₂O₃ ceramic laser at ~1.6 μm using in-house fabricated low scattering loss ceramic sample and in-band pumped by an Er,Yb fiber laser at 1535 nm. Narrow linewidth and tunable laser operation has been realized using intracavity etalon of proper thickness for wavelength tuning and mode selection, yielding a wavelength tuning span of ~89 nm in the range of 1574.4 nm–1581.1 nm, 1599.4 nm-1601 nm, 1637 nm-1641.8 nm, and 1661.4 nm–1663 nm, respectively. Single-longitudinal-mode operation was confirmed using a scanning Fabry–Perot interferometer in the whole wavelength tuning range when output powers lower than ~35 mW.
