We present measurements of the spatio-temporal evolution of a hot-dense plasma generated by the interaction of an intense 25 femtosecond laser pulse with a solid target, using pump-probe two-dimensional Doppler spectrometry. Measuring the time-dependent Doppler shifts at different positions across the probe beam, we achieve velocity mapping at hundreds of femtoseconds time resolution simultaneously with a few micrometer spatial resolution across the transverse length of the plasma. Simulations of the interaction using a combination of 2D particle-in-cell (PIC) and 2D radiation hydrodynamics codes agree well with the experiment. |
