An attempt was made to separate thermal from electronic effects during laser sputtering of gold by partitioning the target surface energy between steady-state electron beam heating and pulsed laser heating. For flat starting surfaces and a peak surface temperature of ∼ 2700 K, the Au translational energy remains (2 − 3) × higher than classical expectations and is insensitive to how energy is partitioned between steady-state heating and laser heating. The mean desorption energy is linearly dependent on peak surface temperature, but with a slope of 15kBT as opposed to the classical 2kBT. © 1996 American Physical Society.
