Observation of superheating during picosecond laser melting

Abstract The surface temperature of GaAs during pulsed laser heating is obtained from the measured velocity distributions of evaporated atoms. For nanosecond pulses the observed solid-liquid transition temperature agrees with the equilibrium melting point. It is shown that with picosecond pulses the solid is superheated by several hundred degrees.
