Resonant photoionization dynamics during optical trapping of lithium atoms
K. Foster, S. Majumdar, D. Fischer
Photoionization induced by trapping and auxiliary laser fields is an inherent feature of many laser-cooling and optical trapping experiments, yet its microscopic dynamics are rarel…
A delay-programmable two-color femtosecond source for multiphoton ionization studies based on chirped-seed NOPA
Kyle Foster, Shruti Majumdar, Mason Toombs +2
We demonstrate a delay-programmable two-color femtosecond source based on a chirped-seed noncollinear optical parametric amplifier. Introducing controlled dispersion into the seed…
A Continuous Pump-Probe Experiment to Observe Zeeman Wave Packet Dynamics
Kevin L. Romans, Kyle Foster, Shruti Majumdar +4
In this work, we study the coherent dynamics of an atomic Zeeman wave packet using a continuous pump--probe scheme. A polarized wave packet is generated via few-photon excitation b…
Time-resolved 3D momentum spectroscopy in continuous wave atomic photoionization
Kevin L. Romans, Bishnu P. Acharya, A. H. Nishshanka. C. De Silva +3
An experimental continuous-wave (cw) pump-probe scheme is demonstrated by investigating the population and photoionization dynamics of an atomic system. Specifically, Li atoms…
