An erbium-doped, silica-based fiber laser was electronically tuned over two ranges from 1529.6 to 1533.3 nm and from 1543.8 to 1563.0 nm with more than 13 mW of maximum power. The tuning element was an intracavity acousto-optic modulator (Bragg cell) configured to feed back the first-order, frequency-shifted deflected beam. The maximum optical/acoustic tuning coefficient was −15 nm/MHz.
