Abstract

Crystal growth, optical absorption and stimulated-emission are studied for Eu-doped monoclinic double tungstates, KRE(WO₄)₂ (with RE = Gd or Y). Free-running and Q-switched pulsed visible (702.8 nm, ⁵D₀→⁷F₄ transition) lasers, as well as quasi-CW and real-CW ones are realized with this crystal family, for the first time, to our knowledge.
