Abstract

A laser material has the composition AHaF.yM, where A is one or more of calcium, strontium or barium, Ha is one or more of chlorine, bromine, or iodine, F is fluorine, M is Sm+2, Tm+2 or U+3, and y is between 10-6 and 10-1. The material may be made by heating the components under an atmosphere of hydrogen and a rare gas, and single crystals grown, e.g. by zone melting.
