摘要
作者研制了一种带有半导体激光器(LD)寿命检测的驱动电源,该电源通过高精度的采样电路和分步调整方式,不仅可以达到恒功率控制,而且能够检测LD的工作寿命,具有寿命预告警、失效保护功能,从而保证LD工作的可靠性、连续性。
A new driver with end-of-life detection for LD is designed, which not only can achieve steady power control, but also can detect run longevity of LD, alarm end - of- life of LD ahead of time, protect the circuit when disabled with high precision sampling circuits and adjustable controls step by step, thereby, and ensure that LD runs reliably and safely.
