According to the operation principle and the rate equation of semiconductor laser, a simulation system of the semiconductor laser based on LabVIEW has been developed. The system has a brief navigating interface, simple operation and good interaction. It can simulate and display the output of a semiconductor laser work on free-running conditions. Students can modify many parameters of the laser and then the system shows the results of simulation. In this way, students can make a comprehensive understanding to operating characteristics of semiconductor laser and influences by operating parameters. The simulation system can be used in the procedure of preparation and teaching of the experiment. It is an auxiliary tool for improving teaching effect.
