- Abstract
We present a method for calibrating a commercial thermal camera adopted to accurately measure the temperature change of the sample in a laser-induced temperature modulation spectrum (LITMoS) test, which is adopted for measuring two crucial parameters of the external quantum efficiency η e x t and the background absorption coefficient α b for assessing the laser cooling grade of the rare-earth-doped materials. After calibration, the temperature resolution of the calibrated thermal camera is better than 0.1 K. For the cooling grade Czochralski-grown 5% Yb3+:LuLiF4 crystal, the corresponding values of η e x t and α b are LITMoS = measured to be η e x t = 99.4 (± 0.1) % and α b = 1.5 (± 0.1) × 10 − 4 cm − 1 , respectively.
