Abstract: Transparent Neodymium Aluminium Barium Borate (NABB) rods, 60 mm long and 5 mm in diameter, have been grown using a Floating Zone (FZ) apparatus. The preparation of sintered feed rods and growth conditions are presented. The vibrational spectra (IR and Raman) of the rods were compared with those of Neodymium Aluminium Borate (NAB) crystals grown from flux. The spectra confirmed the presence of BO3 network which had been identified to have more advantages when compared to the silicates. The absorption and the fluorescence spectra obtained for the sample demonstrates its efficiency for use as a laser material.
