Shock compression of molybdenum under impact of ultrashort laser pulses

The behavior of molybdenum under the action of load pulses of picosecond duration is studied in an experiment. Using the method of spectral interferometry in the single-exposure mode in the picosecond range, changes in the phase and amplitude of the diagnostic pulse reflected from the free surface of the sample are recorded. In a film sample of molybdenum of submicron thickness, compressive stresses reaching $89$ GPa are realized and are accompanied by a significant increase in the surface reflectance.
