摘要：

Interaction of a moderately intense (I approximate to 10 MW cm(-2)), infrared (lambda = 12 mu m), short pulse (1 ps) free-electron laser beam with a gold surface is found to cause an intense electron emission (on the order of 1 mA cm(-2)) and a corresponding 'hot' electron spectra (up to a few eV). We show that heating of the electrons through classical acceleration by the laser electric field in the presence of collisions is a possible explanation for such observations.
