Laser Photoelectric Effect at Surface of Discharge Cathode

Abstract

The photoelectric effect is produced by a glow discharge cathode irradiated by a continuous Carbon Monoxide laser; this photoelectric effect is not related to the frequency of incident light (that is nonresonant absorption photoelectric current) but is only proportional to the intensity of incident light. Moreover, the photocurrent produced by a unit of light intensity is very sensitive to discharge current, gas composition, and gas pressure. A high temperature photoelectron emission mechanism at the cathode surface is described. Chinese language; Translations.
