“…The Aurore beamline 5 is dedicated to investigation of relaxation dynamics in small quantum systems: molecules and nano-particles. The long-term stability of the laser pointing and intensity of Aurore allow to record static 80 or time-resolved photoelectron 8,43,[81][82][83][84] or ion imaging [85][86][87] for more than 12 hours without any realignment.…”

We present the Aurore platform for ultrafast sciences. This platform is based on a unique 20 W, 1 kHz, 26 fs Ti:Sapphire laser system designed for reliable operation and high intensity temporal contrast. The specific design ensures a high stability in terms of pulse duration, energy and beam pointing necessary for extended experimental campaigns. The laser supplies 5 different beamlines, all dedicated to a specific field: attosecond science (Aurore 1), ultrafast phase transitions in solids (Aurore 2 and 3), ultrafast luminescence in solids (Aurore 4), femtochemistry (Aurore 5). The technical specifications of these five beamlines are described in details and examples of recent results are given.

Nolinear Absorption of CT TFF + aggregates in PMMA matrix was studied with resonant excitation around 800 nm in the femtoseconds regime with the Z-Scan technique with 100 Hz pulse repetition rate. The saturated absorption profiles were fitted with a prepared formula based on steady state rate equations for a homogeneous ensemble of two levels systems, thin samples and quasi monochromatic field without the usual assumption of low saturation regime. The lifetime of the CT state, with the use of this model was estimated in hundred of fs, of the same order of magnitude of the exciting pulse.

The photodissociation dynamics of 2-iodotoluene following excitation at 266 nm have been investigated employing femtosecond time-resolved mass spectrometry. The photofragments are detected by multiphoton ionization using an intense laser field centered at 800 nm. A dissociation time of 380±50 fs was measured from the rising time of the co-fragments of toluene radical (C7H7) and iodine atom (I), which is attributed to the averaged time needed for the C−I bond breaking for the simultaneously excited nσ* and ππ* states by 266 nm pump light. In addition, a probe light centered at 298.23 nm corresponding to resonance wavelength of ground-state iodine atom is used to selectively ionize ground-state iodine atoms generated from the dissociation of initially populated nσ* and ππ* states. And a rise time of 400±50 fs is extracted from the fitting of time-dependent I+ transient, which is in agreement with the dissociation time obtained by multiphoton ionization with 800 nm, suggesting that the main dissociative products are ground-state iodine atoms.
