Design and Implementation of an Integrated Parametric Test System of Laser

A semiconductor laser integrated parametric testing and experimental system is designed and implemented.Its main principle is to control the laser driving circuit and the laser temperature control circuit by microprocessor,then collect the data of voltage and current and optical power of laser with the changing of driving current or temperature.These data can subsequently be loaded on a computer for processing and drawing the graph by serial port.With the testing and experimental system, integrated parameters of laser can be tested.Meanwhile this system also can be used in the comprehensive experiment of photoelectric technology and the training of professional comprehensive practical ability.
