| 英文摘要 | Automatic power control of a semiconductor laser (12, 72) is achieved by monitoring the spontaneous lateral emissions from the semiconductor laser and adjusting the drive signal to the laser based on the detected emissions. A lateral detector (13, 73) generates a photocurrent from the spontaneous emissions. The detector signal (Ilat) is compared to a reference signal (Iref) and the difference is applied to the drive signal (Ilas) to alter or control the laser output. The magnitudes of the reference signal source and the drive signal source are determined and set based on the desired optical output power of the semiconductor laser measured at a series of temperatures. |
