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…
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…
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…
A pump-probe experiment in cw-mode on ionization of Rydberg atoms
K. L. Romans, A. H. N. C. De Silva, B. P. Acharya +3
Rydberg atoms are in the focus of intense research due to the peculiar properties which make them interesting candidates for quantum optics and quantum information applications. In…
Two-path interference in the resonance-enhanced few-photon ionization of atoms
B. P. Acharya, S. Dubey, K. L. Romans +6
We investigate the resonance-enhanced few-photon ionization of atomic lithium by linearly polarized light whose frequency is tuned near the 2s-2p transition. Considering the direct…
Magnetic Dichroism in Few-Photon Ionization of Polarized Atoms
B. P. Acharya, M. Dodson, S. Dubey +7
We consider few-photon ionization of atomic lithium by linearly polarized femtosecond laser pulses, and demonstrate that asymmetries of the electron angular distribution can occur…
Circular Dichroism in Atomic Resonance-Enhanced Few-Photon Ionization
A. H. N. C. De Silva, T. Moon, K. L. Romans +8
We investigate few-photon ionization of lithium atoms prepared in the polarized 2() state when subjected to femtosecond light pulses with left- or right-handed circ…
Using circular dichroism to control energy transfer in multi-photon ionization
A. H. N. C. De Silva, D. Atri-Schuller, S. Dubey +9
Chirality causes symmetry breaks in a large variety of natural phenomena ranging from particle physics to biochemistry. We investigate one of the simplest conceivable chiral system…
Photo-ionization of polarized lithium atoms out of an all-optical atom trap: A complete experiment
F. Thini, K. L. Romans, B. P. Acharya +8
An all-optical, near-resonant laser atom trap is used to prepare an electronically excited and polarized gas target at mK-temperature for complete photo-ionization studies. As a pr…
