Abstract

A preliminary discussion is given of electron-positron pair production by means of electrons accelerated to relativistic velocities at the focus of a laser beam. First, the pair cross-section was numerically evaluated near its energy threshold. Then, two methods of relativistic electron production by focused laser light were considered: the coherent oscillation of electrons, and the acceleration of a few high velocity electrons by plasma waves excited by laser-driven instabilities. It was found that the first method would produce pairs for neodymium laser light which is close to the limits of achievable intensities (1019–1020 W/cm2). The second method, however, may be capable of producing pairs at lower intensities.
