Jp. Girardeaumontaut et al., DEPENDENCE OF FEMTOSECOND SINGLE-PHOTON PHOTOEMISSION FROM GOLD ON LASER-BEAM INCIDENCE AND POLARIZATION, Applied physics letters, 63(5), 1993, pp. 699-701
We report here the measurements of single-photon photoelectric emissio
n sensitivity of gold irradiated with 450 fs laser pulses at 248 nm an
d discuss the dependence of this sensitivity on the angle of incidence
and the states of polarization of the laser beam. We compare our expe
rimental data to the predictions from both the vectorial photoemission
theory and the single-photon absorption corresponding to a pure energ
y coupling.
