Abstract
In this work the transition probabilities, radiative lifetimes and branching ratios of Er3+ ions in KY1âxâyGdxLuy(WO4)2 crystals have been determined. With this aim, Er3+ doped KY1âxâyGdxLuy(WO4)2 crystals have been grown by means of the high temperature Top-Seeded Solution Growth. A spectroscopic analysis of Er3+ ions in this crystal has been performed following anisotropic Judd-Ofelt analysis to obtain basic spectroscopic properties. A quantum efficiency over 97% has been determined for the 4I13/2â4I15/2 transition, indicating that this material is adequate for the development of lasers and amplifiers working in the third telecommunication window.
