We report on the growth, spectroscopic and laser characterization of a novel monoclinic laser crystal, Yb,In:KLu(WO4)2 (Yb,In:KLuW). The absorption, stimulated-emission and gain cross-section spectra of 3.5at% Yb, 5.5at% In-doped KLuW are determined at room temperature with polarized light and compared with those for Yb,In:KYW, as well as singly Yb-doped KLuW and KYW crystals. It is found that the...
Terbium (Tb3+) ions are promising for the development of visible lasers. We report on the spectroscopy of Tb3+ in the monoclinic KYb(WO4)2 (KYbW) crystal, including the Judd-Ofelt (J-O) modelling of the transition probabilities, evaluation of the absorption and stimulated-emission (SE) cross-sections with polarized light, and emission lifetime study. Within the strong configuration interaction (SCI)...
