Abstract
Photoemission from a diamond turned copper mirror with laser beams of intensity 10(11) W/cm2 at the photon energy of 2 eV and pulse duration of approximately 300 fs indicates that the electric field associated with the photons enhances the photoemission. At the optimum incident a ngle, the electron yield with p-polarized light was 75 times larger th an that with s-polarized light and four times larger than that at norm al incidence for a constant energy. These enhancements were underestim ated by the changes in the absorption and were attributed in this pape r to the optical field effect.
