摘要：

A structurally disordered Ho3+:LiGd(MoO4)(2) crystal has been grown by the Czochralski method. The absorption and emission properties have been investigated in depth to predict its potential for lasing in the visible and infrared regions. The Judd-Ofelt theory has been applied to evaluate the important optical parameters relevant for laser applications, including the phenomenological intensity parameters, radiative transition rates, branching ratios and radiative lifetimes. The prospect for the crystal as a new laser active medium has been discussed on the basis of the calculated emission cross-sections and quantum efficiencies. The results propose the possibility of the Ho3+:LiGd(MoO4)(2) crystal for applications in the resonantly pumped 2.0 mu m lasers.
