Fast coalescence in island metal films placed on a transparent dielectric substrate has been observed under pulsed laser irradiation of nanosecond duration. The coalescence is caused by liquid-like sintering of islands which form contacts due to either initial non-equilibrium shape transformation or due to island motion under pulsed irradiation. The kinetics of the coalescence depends on the morphology of the island film. The temperature distribution around islands is analysed for various coatings and island sizes, and mechanisms of surface mass transfer are discussed.
