摘要：

In this paper we show how the quantum efficiency of Nd3+-doped laser crystals can be measured by means of a very simple method. This method is based on a multiwavelength study of pump-induced crystal heating, and its major advantage is the simplicity of the required experimental set-up. It has been used to determine the quantum efficiency of the main infrared laser channel (F-4(3/2) --> I-4(11/2)) of the Nd3+:Gd-2(MoO4)(3) non-linear laser crystal. The value obtained for the quantum efficiency (phi = 0.97) is in good agreement with that obtained from the Judd-Ofelt formalism (phi = 0.95).
