Abstract

A single crystal essentially consists of XM.sub.z M'.sub.1.sub.-z P.sub.4 O.sub.12, (0<z.ltoreq.1) in which X is lithium and/or sodium, M is neodymium, and M' is yttrium, lanthanum or gadolinium. Said single crystal can be used as a dielectric active medium for lasers, and can be prepared in the form of a bar having a square cross section measuring 5 mm on each side by the top-seeded solution growth method.
