The effect of In 3+ ion on the optical characteristics of Er 3+ ion in Er/Yb:LiNbO 3 crystal under 980nm excitation has been investigated. The Er and Yb contents in the crystals were measured by an inductively coupled plasma atomic emission spectrometer (ICP-AES). A significant enhancement of 1.54μm emission was observed for Er/Yb:LiNbO 3 crystal doped with 1mol% In...
