AI Technical Summary
The temperature control of existing lasers relies on external thermistors, which have slow response, are located away from the heat source, have large thermal inertia, and are difficult to integrate. This makes it difficult to accurately reflect the temperature changes in the laser's active area in real time, resulting in the kink phenomenon not being used as a failure warning signal, affecting the reliability and safety of the laser.
A laser is designed with a temperature warning zone introduced. By stably limiting the occurrence of the kink phenomenon within this zone and limiting its maximum temperature below the laser failure temperature, the kink phenomenon is used as an internal warning signal to achieve autonomous health status monitoring and timely response to the laser.
It implements the internal temperature monitoring mechanism of the laser, improves the system integration and thermal response efficiency, provides a stable and repeatable early warning signal, ensures that the laser responds in time before failure, avoids failure caused by overheating, and improves the safety and stability of the laser.
