Oscillating frequency and output stabilizer for semiconductor laser
专利汇可以提供Oscillating frequency and output stabilizer for semiconductor laser专利检索，专利查询，专利分析的服务。并且PURPOSE: To stabilized oscillating frequency and output of a semiconductor laser for a long period by providing a specific inrush current supply source, an oscillating output variation detector, an oscillating wavelength variation detector, a heat quantity detector, an operating temperature stabilizer and an inrush current controller.
CONSTITUTION: An inrush current supply source 15, an oscillating output variation detector 16, a photodetector 45 for detecting part of the oscillation output through an optical element for varying spectral characteristic in an oscillation wavelength range, and an oscillating wavelength variation detector 44 having a processor 41 for obtaining the variation in the oscillating wavelength on the basis of the output of the photodetector and the output of the detector 16 are provided. Further, a generated heat quantity detector, an operating temperature detector, a thermoelectric effect element for heat transfer with a semiconductor laser 1, an operating temperature stabilizer 13 having an operating temperature controller 17 for controlling a thermoelectric effect element so that the operating temperature coincides with the set temperature while holding the oscillation output constant on the basis of a reference signal corresponding to the set temperature, the output of the generated heat detector and the output the detector 16, and an inrush current controller 14 for controlling the inrush current of the supply source 15 so that the oscillation wavelength becomes constant on the basis of the output of the detector 44 are provided.
