摘要：

In this paper, the quantum efficiency of the YAl3(BO3)(4):Nd laser crystal has been measured using a method based on the simultaneous measurement of photoacoustic and photoluminescence signals within a broad wavelength excitation range (700-850 nm). A quantum efficiency Phi = 0.26 +/- 0.05 is determined. This low quantum efficiency is explained id terms of a high multiphonon relaxation rate from the metastable state F-4(3/2) involving about three effective phonons of energy 1346 cm(-1).
