Paper Abstract

Electron emission from the surface of copper target irradiated with femtsecond pulsed laser (wavelength 800nm, pulse width 100fs) was measured at the atmospheric pressure. A tiny metal probe was used to detect the electric potential made by the charged particles. It was found that the energy of emitted electrons became higher gradually when laser irradiation was repeated on the same spot.
