✦ Synopsis

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 photocmission 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{ 1 I1 ] single crystal, and the experimental results confirm, for the first time, that the theory is valid in this temperature regime.

Recently, Zenobi, Hahn and Zare introduced thin-film resistance sensors for the surface temperature measurement of dielectric materials heated by pulsed laser radiation. They concluded that absorption or reflection by their thin-film sensor is in any case negligible, thus causing no systematic error

Pulsed laser powered homogeneous pyrolysis ( LPHP) is a technique which can be used to measure rate parameters for purely homogeneous unimolecular decomposition reactions at high temperatures (600-1500 K). The reaction temperature in pulsed LPHP may be obtained from the speed of sound in the reactin
