Electro-optic signals for different experimental conditions. (a,b) Single-shot snapshots obtained when the laser is focused on the tip (0.0.7μm thickness) of the target with 50% (a) and 100% (b) energy. The signature of two escaping electron bunches is also detected. (c,d) The laser pulse with a fixed energy (50%) is now focused on the tip (c) and bulk (6 μm thickness, d) of the target, resulting in partial and full energy deposition, respectively. The probe laser was delayed by 4 ps in (c,d) with respect to (a,b), resulting in a signal shift toward left.
