| 摘要 |
The invention is directed to a system and a method for controllably broadening the spectral characteristics, such as the emission linewidth, of a semiconductor laser (24) by discharging an electric pulse, for example, a charged transmission line (20), across the laser terminals. The linewidth-broadened lasers find application in fiber optic sensors, such as fiber optic gyroscopes and current sensors, which have a relatively short de-coherence length.
