| Abstract: | The temperature greatly influences the characteristics of laser diode. If a stable output wavelength is required, the temperature of the laser diode must be maintained at a constant level. In this paper, the principle and the method for accurately controlling the temperature of the laser diode are described. The structure of the temperature controlling system and the electronics of the thermoelectric cooler are given. By using this system, the temperature accuracy of 0.02 t can be obtained. |
