An unusual solidification pattern was found to occur in thin coper films following pulsed laser irradiation, under limited conditions of pulse length and beam power. Two phases of different crystal size and orientation are obtained. Simulations of the temperature distribution during and after the laser pulse together with a morphological analysis suggest that the two phases result from two different solidification mechanisms.
