Previously, strong-field-induced ionization and fragmentation of PAHs were studied with table-top laser setups. In particular, laser pulses with peak intensities of about ∼ 10 14 W/cm 2 interacting with PAHs have produced ionic species up to tetracations. Investigations of the ultrafast ionization and fragmentation of PAHs induced by highly energetic XUV photons have recently gained attention in the scientific community for tracing down mechanisms of photochemical reactions. The ultrafast pumpprobe studies with ultrashort XUV pulses produced either by highharmonic generation (HHG) sources or free-electron lasers (FELs) revealed rich dynamics of charge state evolutions up to PAH trications. Femtosecond strong-field laser pulses, produced by Ti:Sa lasers, were also used to induce dynamics in benzene and toluene. These studies found interesting dynamics, such as oscillations between vibrational states in toluene, or conical intersection relaxation in Jahn-Teller benzene cations. In this work, we present an investigation of the dynamics of a three-ring PAH fluorene (C 13 H 10 , FLU, see Figure ). This molecule can be thought of as a three-ring analog of indene, the first pure PAH identified in the ISM. The XUV-induced dynamics of FLU have recently been studied in detail. As a follow-up, here we chose to investigate how the observed dynamics change in a different excitation regime. We used ultrashort strong-field infrared (IR) laser pulses to excite FLU and subsequently probed it using a weaker visible (VIS) pulse. The pump pulse peak intensity was estimated to be 3.3 × 10 13 W/cm 2 , which corresponds to a Keldysh parameter value of γ = 1.4, for the single ionization of FLU. Based on the calculated γ value and considering a nonuniform spatial distribution of intensities in the laser pulse, we expect to observe a mixed regime of strong-field ionization that could show features of both tunneling ionization (TI, γ ≪ 1) and multiphoton ionization (MPI, γ ≫ 1). The interaction of the strong-field laser with FLU results in the production of electrons and multiple ions, which were measured using a double-sided velocity map imaging (VMI) spectrometer. VMI enabled the disentangling of the various photodissociation fragmentation pathways on the basis of momentum. In addition, the time-of-flight (TOF) mass spectra (MS) of the ions were measured. This multi-channel data accumulation allowed for a detailed and comprehensive decomposition of the strong-field-induced dynamics of FLU. In this manuscript, we describe the experimental details, data analysis, and theoretical calculations. This is followed by pump-probe independent results, dynamical observations, and conclusions.
