Abstract

The fluorescence dynamics from excited states of Er3+ in KY(WO4)2 are compared with Judd–Ofelt-theory calculations, and spectroscopic parameters of the promising laser transitions from the 4I13/2,4I11/2, and 4S3/2 levels are determined. The cw excited-state absorption spectra of Er3+-doped KY(WO4)2 are measured with a pump-and-probe technique and analyzed in the spectral range from 500 nm to 1800 nm. Energy transfer between Yb3+ and Er3+ ions in codoped KY(WO4)2 is investigated. Laser action near 1.54 μm under Ti:sapphire and diode-laser pumping is obtained in Er,Yb:KY(WO4)2.
