Title: Angle-resolved non-resonant two-photon single ionization of argon using 9.3 eV photons produced via high harmonic generation
Authors: Kirk A. Larsen, Daniel S. Slaughter, Thorsten Weber
Abstract summary: We present an experimental study on the photoionization dynamics of non-resonant one-color two-photon single valence ionization of neutral argon atoms. Using 9.3 eV photons produced via high harmonic generation and a 3-D momentum imaging spectrometer, we detect the photoelectrons and ions produced from non-resonant two-photon ionization in coincidence.

Abstract: We present an experimental study on the photoionization dynamics of non-resonant one-color two-photon single valence ionization of neutral argon atoms. Using 9.3 eV photons produced via high harmonic generation and a 3-D momentum imaging spectrometer, we detect the photoelectrons and ions produced from non-resonant two-photon ionization in coincidence. Photoionization from the $3p$ orbital produces a photoelectron scattering wave function with $p$ and $f$ partial wave components, which interfere and result in a photoelectron angular distribution with peak amplitude perpendicular to the VUV polarization. The comparison between the present results and two previous sets of theoretical calculations [Pan, C. & Starace, A. F. (1991). $\textit{Physical Review A}$, 44(1), 324., and Moccia, R., Rahman, N. K., & Rizzo, A. (1983). $\textit{Journal of Physics B: Atomic and Molecular Physics}$, 16(15), 2737.] indicates that electron-electron correlation contributes appreciably to the two-photon ionization dynamics.

Hot-Band Absorption Can Mimic Entangled Two-Photon Absorption [52.77024349608834]
We investigated the fluorescence signals from Rhodamine 6G and LDS798 excited with a CW laser or an entangled photon pair source at 1060 nm. We observed a signal that originates from hot-band absorption (HBA), which is one-photon absorption from thermally-populated vibrational levels of the ground electronic state. For the typical conditions under which E2PEF measurements are performed, contributions from the HBA process could lead to a several orders-of-magnitude overestimate of the quantum advantage for excitation efficiency.

We present a combined experimental and theoretical study on the photodissociation dynamics of ion-pair formation in O$$ following resonant two-photon absorption of a 9.3 eV femtosecond pulse. Ion-pair formation states of $3Sigma-_g$ and $3Pi_g$ symmetry are accessed through predissociation of optically dark continuum Rydberg states converging to the B $2Sigma-_g$ ionic state.
