Explore the revolutionary field of attosecond physics in this Stanford Physics lecture where Nobel laureate Anne l'Huillier demonstrates how extreme ultraviolet light sources based on high-order harmonic generation create incredibly short light bursts lasting only 100 attoseconds, enabling unprecedented temporal resolution for atomic studies. Learn how these attosecond pulses have transformed our ability to investigate atoms, allowing scientists to measure minute time delays in photoionization processes and observe phase changes of electrons across resonances. Discover cutting-edge research techniques including quantum state tomography methods used to determine photoelectron quantum states, and gain insights into how this groundbreaking technology opens new frontiers in understanding atomic-scale phenomena at timescales previously impossible to observe.
