Abstract

Luminescence spectra of Tm³⁺ ion have been investigated for YVO₄ and LiNbO₃ crystals by excitation with 798 nm laser diode of high powers in a range from 0.6 W up to 10 W. In addition to the one-photon excited infrared emission bands, emission bands at 700 and 1208 nm are observed in YVO₄ by high power excitation and the similar emission bands are observed at 702 and 1216 nm in LiNbO₃. It is observed that each of the 700 and 1208 nm emission intensities in YVO₄ has quadratic pump-power dependence in a pump power range of 0.6 - 4 W and cubic dependence in 4 - 10 W range. Same result is observed for the 702 and 1216 nm emission in LiNbO₃ but the change from the quadratic to cubic dependence appears at 5 W. Discussion is made on the luminescence process for these up-conversion.
