Laser induced neutral particle emission was observed. When Al surface was irradiated by a Q-switched YAG 532nm beam with energy density below 2J·cm-2, only neutral atoms were detected. The amount of ejected atoms and their kinetic energies were measured as a function of laser fluence. Both the results indicate that increase of the surface temperature exceeds several thousands Kelvin, and the mechanism of atom emission around this energy region follows statistical thermodynamics.
