Probing thermal dissipation dimensionality to laser ablation in the pulse duration range from 300 fs to 1 µs.We propose a quantitative method to determine the thermal dissipation dimensionality to laser ablation.  We derived an analytical expression for the melting condition due to a single pulse for arbitrary spot diameters and pulse durations, which explicitly contains the dimensionality of the thermal diffusion process.  The result shows that the thermal dissipation processes dominate for pulse durations longer than 5 ps, while nonthermal processes begin to dominate for shorter pulse durations.
