Abstract;An electrostatic plasma micro-undulator was formed experimentally using a combination of laser interference and resonant photoionization techniques. Plasma micro-undulator of this type are expected to be applied as compact and short-wavelength insertion devices. Stable microscopic interference fringes were obtained using a prism as an optical device for interference, and atomic vapor was resonantly ionized by this interfered laser beam. As a result, an emission from plasma corresponding to interference fringes, with periodic length of about 300.MU.m, was obsderved. Thus, formation of a plasma micro-undulator was demonstrated by these techniques. (author abst.)
