Abstract

A no mode hopping and narrow linewidth external-cavity wavelength-swept laser (EC-WSL) based on a traditional Littman-Metcalf structure is proposed and experimentally demonstrated. The wavelength scanning output range of the proposed laser without mode hopping is from 1520.82 nm to 1579.95 nm (namely, 59.13 nm). The narrow spectral linewidth less than 100 kHz is simultaneously realized. Meanwhile, the output power of the presented laser exceeding 14.8 dBm over the entire wavelength scanning range is obtained. In view of the good tuning characteristics, we achieved now, the proposed EC-WSL may be used in practical engineering fields such as gas detection.
