Abstract:
A photocathode apparatus is constructed by a transparent body adapted to receive incident light, and a metal cover layer formed on a surface of the transparent body. The incident light reaches an incident/reflective surface of the metal cover layer through the surface of the transparent body to excite surface plasmon resonance light in the incident/reflective surface of the metal cover layer, thus emitting photoelectrons from a photoelectric surface of the metal cover layer opposite to the incident/reflective surface thereof by the photoelectric effect of one of the surface plasmon resonance photons and its second harmonic generation wave.
