Abstract

We extend the analysis of Trebino (Appl. Opt. 24, Apr. 15, 1985) of single-material achromatic prism beam expanders to include two-material devices and practical expanders consisting entirely of commercially available 45-45-90 prisms. We show that sacrificing simultaneous achromaticity and thermal stability allows the construction of two-material prism beam expanders with only one of these two properties, but having significantly greater transmission than a similar-magnification single-material device. Finally, a numerical optimization routine yields optimal incidence angles for two-, three-, and four-prism single-material achromatic prism beam expanders. In general, we find that the "up-up-...-up-down" configuration is optimal in nearly all practical cases.
