Paper Abstract

The emitting frequency of a diode laser is very sensitive to operating temperature. In the design of the temperature controller of a diode laser, it is important that the control parameters of PID should be tuned to match with the characteristic of the controlled target in order to get an optimal correcting effect. In the experiments, two methods of determining PID parameters, Ziegler-Nichols and critical level of proportion methods, were used, and the approximate same results were obtained. The measured result shows the controlling precision of the temperature controller is ±2m°C after PID parameters are tuned.
