Abstract: Prolific electron-positron pair production is possible at laser intensitiesapproaching 10^{24} W-cm^2 at a wavelength of 1 micron. An analysis of electrontrajectories and interactions at the nodes B=0 of two counter-propagating,circularly polarised laser beams shows that a cascade of gamma-rays and pairsdevelops. The geometry is generalised qualitatively to linear polarisation andlaser beams incident on a solid target.
