The Research of Controlling Constant Temperature for Semiconductor Laser Diodes

摘要

This paper introduces two types of precise temperature controllers for high power semiconductor laser diodes. We apply a category of self-tuning parameter fuzzy-PID controller, and a kind of neuronal network optimized rules fuzzy-PID controller to realize stable temperature controlling, we simulate these two methods by Matlab. The result proves that the new method has more superiority than traditional means, such as PID controlling, etc. And further improvement on constant temperature control will inevitably promote the reliability of LD.
