        The authors have developed a driving power supply with semiconductor laser lifetime detection. Through high-precision sampling circuits and step-by-step adjustment methods, this power supply can not only achieve constant power control, but also detect the working life of LD. It has lifetime early warning and failure protection functions, thereby ensuring the reliability and continuity of LD operation.
