| 摘 要： | 传统LD驱动电源通常采用电流参数预定输入的方式,其只能输出给定脉宽、重复频率及峰值的驱动电流,这种方式注定其不能随工作环境的变化而做相应调节。针对上述传统LD驱动电源的固有缺点,介绍一种具有温度自适应调节的LD驱动电源,该电源通过微处理器FPGA芯片检测LD的工作温度,采用温度补偿算法,做到自适应调节驱动电流的大小,实现LD驱动电源的智能化运行,使LD在不同温度下稳定工作。

| Abstract: | The traditional operating method of LD power driver is that the user preset the parameters of drive current such as the rate,pulse width and amplitude.The LD cannot adjust its working parameters according to the variation of its environment with this method.A new tempreture adaptively adjustable driver for high power laser is proposed,which can detect the tempreture variation of the LD and adjust its drive current according to the detected temperature.With this method the LD can work steadily in broader range of temperature. |

| Keywords: | laser technique LD power driver temperature adaptively adjust stability of optical output |
