摘要：

Pulsed laser-induced two-photon photoemission has been used as a probe of the instantaneous heating of a single crystal surface by the laser pulse itself. The high kinetic energy edge of the photoemission spectra are fitted to Fermi-Dirac distributions to determine substrate lattice temperatures. Surface temperatures of up to 1000 K are induced by excimer laser pulses on a Rh{111} single crystal, and the experimental results confirm, for the first time, that the theory is valid in this temperature regime.
