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.
