Abstract

For many phased array laser uses such as optical recording or laser beam printing, it is important to focus the output power into a circular diffraction-limited single spot with high efficiency. There are articles using cylindrical lenses for this purpose, but they do not prove that it was diffraction-limited.1 Besides, there has been much interest in single-emitter-diode laser interferometric phase measurements2 and recently in the phased array.3
