Delay in electronic vortex states created by multiphoton ionization with single elliptically polarized laser pulses
Edward McManus, Phi-Hung Tran, Michael Davino +6
We show experimentally and theoretically that vortex-shaped structures in the photoelectron momentum distribution can be observed for atoms interacting with a single intense ellipt…
High Repetition-Rate Pulse Shaping of a Spectrally Broadened Yb Femtosecond Laser
Julia Codere, Michael Belmonte, Brian Kaufman +5
We demonstrate compression and shaping of few cycle pulses from a high average power Ytterbium laser system. The pulses from a commercial 20 W, 100 kHz Yb laser system are spectral…
Long Lived Electronic Coherences in Molecular Wave Packets Probed with Pulse Shape Spectroscopy
Brian Kaufman, Philipp Marquetand, Tamas Rozgonyi +1
We explore long lived electronic coherences in molecules using shaped ultrafast laser pulses to launch and probe entangled nuclear-electronic wave packets. We find that under certa…
Direct Observation of Entangled Electronic-Nuclear Wave Packets
Gonenc Mogol, Brian Kaufman, Chuan Cheng +2
We present momentum resolved covariance measurements of entangled electronic-nuclear wave packets created and probed with octave spanning phaselocked ultrafast pulses. We launch vi…
Filming Enhanced Ionization in an Ultrafast Triatomic Slingshot
A. J. Howard, M. Britton, Z. L. Streeter +10
Filming atomic motion within molecules is an active pursuit of molecular physics and quantum chemistry. A promising method is laser-induced Coulomb Explosion Imaging (CEI) where a…
A plano-convex thick-lens velocity map imaging apparatus for direct, high resolution 3D momentum measurements of photoelectrons with ion time-of-flight coincidence
Michael Davino, Edward McManus, Nora G. Helming +9
Since its inception, velocity map imaging (VMI) has been a powerful tool for measuring the 2D momentum distribution of photoelectrons generated by strong laser fields. There has be…
Strong Field Ionization of Water II: Electronic and Nuclear Dynamics En Route to Double Ionization
Chuan Cheng, Zachary L. Streeter, Andrew J. Howard +6
We investigate the role of nuclear motion and strong-field-induced electronic couplings during the double ionization of deuterated water using momentum-resolved coincidence spectro…
Strong Field Ionization of Water: Nuclear Dynamics Revealed by Varying the Pulse Duration
A. J. Howard, C. Cheng, R. Forbes +6
Polyatomic molecules in strong laser fields can undergo substantial nuclear motion within tens of femtoseconds. Ion imaging methods based on dissociation or Coulomb explosion there…
Coincidence velocity map imaging using Tpx3Cam, a time stamping optical camera with 1.5 ns timing resolution
Arthur Zhao, Martin van Beuzekom, Bram Bouwens +9
We demonstrate a coincidence velocity map imaging apparatus equipped with a novel time stamping fast optical camera, Tpx3Cam, whose high sensitivity and ns timing resolution allow…
Nonadiabatic dynamics and multiphoton resonances in strong field molecular ionization with few cycle laser pulses
Vincent Tagliamonti, Péter Sándor, Arthur Zhao +3
We study strong field molecular ionization using few- (four to ten) cycle laser pulses. Employing a supercontinuum light source, we are able to tune the optical laser wavelength (p…
Strong Field Molecular Ionization in the Impulsive Limit: Freezing Vibrations with Short Pulses
Péter Sándor, Vincent Tagliamonti, Arthur Zhao +4
We study strong-field molecular ionization as a function of pulse duration. Experimental measurements of the photoelectron yield for a number of molecules reveal competition betwee…
