Notes:
Single crystals of LiTaO3 doped with praseodymium were grown by the Czochralski method from congruent melt and their optical properties were examined. It has been found that the Pr3+ ions in LiTaO3 occupy several nonequivalent sites differing in the crystal field strength. In addition, the structural disorder associated with Li deficiency gives rise to strong inhomogeneous broadening of both the optical absorption and emission lines. In contrast to isostructural LiNbO3:Pr, the relaxation of the excited 3P0 level of praseodymium is governed by radiative transitions, which terminate on excited multiplets and make the LiTaO3:Pr3+ crystals promising for four-level lasing in the visible range. © 1997 American Institute of Physics.
