Semiconductor laser array device |
摘要 |
A semiconductor laser array device in which a single photodetector is provided near the exit ports on one side of the semiconductor laser array device that has a plurality of semiconductor lasers arranged close to each other, the light outputs from each of the laser light sources are detected in a time-sharing manner, and the corresponding lasers are controlled by feedback relying upon the detected signals, so that outputs of the lasers are stabilized.
