Abstract
Interaction of a moderately intense (I approximate to 10 MW cm(-2)), i nfrared (lambda = 12 mu m), short pulse (1 ps) free-electron laser bea m 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 spectr a (up to a few eV). We show that heating of the electrons through clas sical acceleration by the laser electric field in the presence of coll isions is a possible explanation for such observations.
