Abstract: In this paper, an ultrashort pulse measurement teaching device based on the autocorrelation method is designed and built, and three comprehensive application experiments are developed to measure the refractive index of unknown transparent medium, the dispersion coefficient of optical fiber and the global information of laser pulse based on the fundamental experiment of laser pulse width measurement. The experimental design fully embodies the physical ideas and scientific research methods of time-resolved technology, which is helpful to enhance students understanding of cutting-edge science and technology in the field of ultrafast laser, and improve their scientific literacy and innovation ability. The setup incorporates CCD and LabVIEW, which makes the phenomenon intuitive, the measurement process automated, and the modern scientific research tools are on track, which helps to stimulate students interest in scientific research. The experimental design for ultrashort laser pulse measurement successfully integrates basic experiments with advanced scientific research, making it suitable for dissemination and application in experimental modern physics courses.

Key words: ultrashort laser pulses, autocorrelation experiment development, scientific research feedback, experimental modern physics
