Research output: Contribution to journalArticleResearchpeer-review


The use of gradient-index lenses, which inherently have fewer surface defects than conventional convex lenses, for laser-beam expansion in interferometry results in improved fringe visibility without loss of light intensity and the need for stringent alignment requirements.
