Abstract

Electrical wavelength-tunable picosecond laser pulses were demonstrated in an actively mode-locked fiber ring laser with a linearly chirped fiber Bragg grating (FBG). Continuous wavelength tuning with a range of 7.2 or 5.8 mm was achieved by changing the modulation frequency respectively around 2.48 or 6.3 GHz. A pulsewidth of about 20 ps was obtained in the entire tuning range, which was limited mainly by the reflection bandwidth of the FBG.
