The state of relaxation of amorphous Ge films has been modified upon melting and rapid solidification induced by irradiation with ps laser pulses. The material obtained upon irradiation with fluences slightly above the melting threshold is less relaxed than the as-deposited one (de-relaxation process). For larger fluences the results obtained suggest that the degree of relaxation is related to the supercooling achieved prior solidification.
