Design and Implementation of Multi-channel Tunable Laser Experiment System

This paper presents a multi-channel tunable laser experimental system which was used in optoelectronic experiment teaching.And expound the relationship between the laser output center wavelength and the driving current.The laser system can adjust the working parameters to achieve one or more outputs of different wavelength of laser.The whole system consists of hardware and software compentens,with multi-function,simple operation,high precision,high integration,working status can be monitored and so on.
