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…
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…
