This report describes the single crystal growth of various laser materials which may be useful in generating new wavelengths. It also includes some compositions of materials which are not availabel commercially but are necessary for test lasers at the Naval Research Laboratory. The host crystals include yttrium aluminum garnet Y2A14012, yttrium lithium fluorides YLiF4, and barium yttrium fluoride BaY2F8. These hosts were doped with singleormultiple rare earth elements for lasing action at wavelengths in the near infrared 1-3 micrmeters. After the crystals were grown, samples were provided in the form of cm size polished rectangular parallepipeds or 5-6 cm cylindrical rods with polished ends. All of the samples were tested or used at laser facilities of the Naval Research Laboratory. No active tests were performed at the crystal preparation source.
