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.
