Fink, J H

This patent describes an apparatus for photoneutralization of an atomic or molecular beam of negatively charged particles, the apparatus comprising: an optical cavity including a first and second end walls, spaced apart and facing one another and having a longitudinal axis extending therebetween; first and second, substantially identical, convex mirrors, spaced apart within the optical cavity and facing one another along the optical cavity longitudinal axis, with the first and second convex mirrors being adjacent to but spaced apart from the first and second walls, respectively; first and second, substantially identical concave mirrors, positioned at the first end wall and at the second end wall, respectively, within the optical cavity and facing one another along the longitudinal axis of the optical cavity; an optical gain cavity that includes the first end wall and the first convex mirror; a photoneutralization region that includes the second end wall and the second convex mirror, with the optical gain cavity being separated from the photoneutalization region by an optical window that provides a substantially gas-tight seal and is transparent to radiation of a predetermined wavelength lambda = lambda/sub r/; gas excitation means, operatively associated with the optical gain cavity, to excite a gas contained in this cavity.
