The luminescent quantum efficiency of the laser emitting level () of ions in lithium niobate () is obtained experimentally by using a method based on the simultaneous and multiwavelength measurement of photoacoustic and luminescent signals after modulated continuous laser excitation. The experimental results give a high luminescence quantum efficiency, (), which is in agreement with the highest of the values reported in the literature from Judd-Ofelt calculations.
