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. Su

The temperature of a dielectric surface irradiated by a laser pulse can be measured by recording the time-resolved resistance change of a thin platinum stripe vapor-deposited on this surface. Results are reported for quartz and glass surfaces exposed to a pulsed COz laser, showing heating rates in e
## METHODS Fabrication of Thermocouple-Light Probe Standard 1 mm glass pipettes were drawn to an outer tip diameter of -50 pm and an interior diameter of -30 pm. An annular thermocouple junction was formed at the tip by vapor deposition of nickel and copper on the pipette. First, a 2,000 A nickel
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
