英文摘要 | An apparatus for stabilizing the wavelength/output power of a semiconductor laser is disclosed. It includes an injection current supplying source for supplying an injection current to a single-mode semiconductor laser; an output power variation detecting portion for detecting the variation of the output power; a wavelength variation detecting portion which has a light receiving portion for receiving a part of the output power of the semiconductor laser through an optical element whose spectral characteristics are varied in the wavelength area of the semiconductor laser and a processing portion for obtaining a variation of the wavelength of the semiconductor laser; an operating temperature stabilizing portion which comprises an operating temperature detecting portion and adapted to detect an operating temperature thereof, a thermoelectric element for forwarding and receiving heat to and from the semiconductor laser, and an operating temperature controlling portion for controlling the thermoelectric element, an output of the heat value detecting portion, and an output of the output power variation detecting portion; and an injection current controlling portion for controlling the injection current of the injection current source. |
