“…The rich emission spectrum and unique chemical characteristics of rare-earth ions have been widely studied as the new darling of the laser material. [3][4][5][6][7] Among them, Ho 3+ which has a special electronic structure has been the most popular activator ion in recent years. Up to now, the up-conversion luminescence properties of Ho 3+ ions-doped crystals have been extensively investigated.…”

A series of LiNbO 3 crystals tri-doped with Mg 2+ , Yb 3+ , and Ho 3+ are grown by the conventional Czochraski technique. The concentrations of Mg 2+ , Yb 3+ , and Ho 3+ ions in Mg:Yb:Ho:LiNbO 3 crystals are measured by using an inductively coupled plasma atomic emission spectrometry. The x-ray diffraction is proposed to determine the lattice constant and analyze the internal structure of the crystal. The light-induced scattering of Mg:Yb:Ho:LiNbO 3 crystal is quantitatively described via the threshold effect of incident exposure energy flux. The exposure energy (E r ) is calculated to discuss the optical damage resistance ability. The exposure energy of Mg(7 mol):Yb:Ho:LiNbO 3 crystal is 709.17 J/cm 2 , approximately 425 times higher than that of the Mg(1 mol):Yb:Ho:LiNbO 3 crystal in magnitude. The blue, red, and very intense green bands of Mg:Yb:Ho:LiNbO 3 crystal are observed under the 980-nm laser excitation to evaluate the up-conversion emission properties. The dependence of the emission intensity on pumping power indicates that the up-conversion emission is a two-photon process. The up-conversion emission mechanism is discussed in detail. This study indicates that Mg:Yb:Ho:LiNbO 3 crystal can be applied to the fabrication of new multifunctional photoluminescence devices.

“…LiNbO 3 (LN) single crystal can be grown and doped with rare earth ions relatively easily [11,12], and it also has splendid optical characteristics as well as excellent chemical and physical stability [13,14]. Therefore, it is competent to use LN single crystal for FIR-OTS purpose.…”
