Electron spectra from strong-field enhanced ionization in heavy water
Eleanor Weckwerth, Chuan Cheng, Ian Gabalski +6
Strong-field enhanced ionization (EI) is a phenomenon in which stretching of interatomic bonds into a distorted molecular geometry leads to an increase in the tunneling ionization…

Optical Interference Effect in Strong-field Electronic Coherence Spectroscopy
Eleanor Weckwerth, Andrew J. Howard, Chuan Cheng +6
We have investigated strong-field-induced electronic coherences in argon and molecular nitrogen ions created by high-intensity, few-cycle infrared laser pulses. This is a step towa…

Orientation-Dependent Enhanced Ionization in Acetylene Revealed by Ultrafast Cross-Polarized Pulse Pairs
S. A. Mohideen, A. J. Howard, C. Cheng +4
We investigate the orientation dependence of Enhanced Ionization (EI) during strong-field-driven nuclear motion in acetylene (CH). Here, we both initiate and probe molecula…
