A virtual simulation experiment platform was developed for the interaction between ultra-fast light field and matter by means of school-enterprise cooperation.On this platform,students could understand the laser’s principle and operation,and the measurement of time-frequency domain distribution,spatial intensity distribution,ultra-fast laser pulse,ultra-fast dynamics and high-resolution spectra.The platform provided a large instrument library including laser light source,optical components,equipment,etc.,which was completely open to users.Users could independently set up the experimental optical path by adjusting relevant experimental equipment,change the relevant parameters of the instrument,observe the experimental phenomena,and realize the data acquisition and analysis,which reflects the real-time man-machine interaction.The design of the virtual simulation platform focused on the learner’s cognitive rules and the educational characteristics of the pedagogical practice.It helped the learners to fully grasp the laser principle and laser spectroscopy technology,and apply them to guide experiment,and improve the understanding.
