The Nova and Novette lasers' focusing lenses, with added cylinder elements, produce line foci for irradiating x-ray laser targets. Design, implementation, and results are discussed. An analysis of the focusing properties of a symmetric lens and cylinder lens combination is presented. It is shown that spherical aberration affects the line width and the intensity distribution in the line focus. In addition, expressions are derived which show that the line foci lie on curved surfaces.
