✦ Synopsis

Nd:LuAG (Nd:Lu 3 Al 5 O 12 ) crystal was grown by the Czochralski method. X-ray powder diffraction experiments show that the Nd:LuAG crystal crystallizes in the cubic with space group Ia3d and has the cell parameter: a = 1.1907 nm, V = 1.6882 nm 3 . The absorption and fluorescence spectra of Nd:LuAG crystal at room temperature were investigated. With a fiber-coupled diode laser as pump source, the continuous-wave (CW) laser action of Nd:LuAG crystal was demonstrated. The maximum output power at 1064 nm was obtained to be 3.8 W under the incident pump power of 17.3 W, with the optical conversion efficiency 22.0% and the slope efficiency 25.7%.

Polarized absorption spectra of Nd:LuVO 4 crystal were measured at room temperature. The optical parameters of π polarization and σ polarization were calculated by Judd-Ofelt theory. Meanwhile, the phenomenological intensity parameters: Ω 2 , Ω 4 , and Ω 6 were obtained, then the parameters were use

## Abstract A Single crystal of FeTi with a diameter of ca 34 mm and a length of ca 48 mm has been grown from a quasi‐stoichiometric melt with an excess of 1% titanium employing the Bridgman technique. Experiments with the Czochralski technique were not successful. The only crucible material suffic
