Abstract:
Time-resolved optical reflection microscopy studies demonstrate spatiotemporal dynamics of melting and ablation of graphite surface molten by single IR femtosecond laser pulses, which are revealed by monitoring picosecond oscillations of the probe reflectivity modulated by transient acoustic reverberations in the surface melt. Temporal periods and amplitudes of the reverberations are affected through transient variations of melt thickness and acoustic impedance by melting, thermal expansion, spallation and fragmentation processes, thus enabling quantitative evaluation of their contributions and basic parameters.
