摘要：

Nonequivalent Er3+ sites in LiNbO3 crystals have been evidenced by low-temperature optical absorption measurements. The radiative transition rates for the S-4(3/2), F-4(9/2), I-4(9/2), I-4(11/2), and I-4(13/2) levels have been evaluated by the Judd-Ofelt method, and the contribution of multiphonon relaxation to the decay of excited states has been estimated. The quantum efficiency of the I-4(11/2) level has been estimated to be 6% only, thus the excitation of levels lower than S-4(3/2) is expected to populate efficiently the I-4(13/2) level.
