| 英文摘要 | A semiconductor laser controller comprising an optical detecting circuit for detecting the output of a semiconductor laser, a first circuit for controlling the semiconductor laser driving current on the basis of a bottom output of the semiconductor laser detected by the optical detecting circuit, a detecting and holding circuit which detects the peak output at the start of the pulse modulation of the semiconductor laser and holds the peak output, and a second means for the feed-forward control of the modulated pulse amplitude of the semiconductor laser after the start of the pulse modulation, whereby the semiconductor laser controller is capable of restricting the change of the peak output of a semiconductor laser resulting from the variation of the quantization efficiency with temperature and passage of time, and stabilizing the peak output within a short time. |
