Abstract

AbstractThe use of titanium-sapphire-laser radiation with a low pulse repetition rate made it possible to operate a metal tip (without its destruction) as an electron emitter at an increased intensity of laser radiation on the tip. As a result, an emission of electrons with a charge in the range of tens of picocoulombs per laser pulse was obtained from a metal tip with a characteristic radius of a curvature of ~1 μm.
