Spencer Walker

Spencer Walker's work focuses on how ultrashort, intense laser pulses interact with atoms and molecules, especially when the light is circularly or elliptically polarized. This includes studying how such pulses ionize atoms, generate high-order harmonics (a way of producing new, often higher-frequency light from an intense laser), and how these pulses can themselves be measured and characterized using techniques like autocorrelation. The research is theoretical/computational, aiming to understand and control electron behavior and light generation at extremely short timescales.

Publication output has grown from sporadic single papers earlier in the decade to a more consistent multi-paper-per-year pace since 2021, peaking in 2024.
