Abstract: The Nobel Prize in Physics 2023 was awarded to three experimental physicists, for their tremendous contribution to "experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter". For the significance and applications of attosecond pulse laser, this paper is organized by the development of human exploration on ultrafast dynamics, the principle and experimental methods of generation and measurements of attosecond pulse laser, typical applications of attosecond pulse laser and future perspectives.

Key words: nobel prize in physics 2023, attosecond pulse laser, high order harmonic generation, electron dynamics
