Abstract

Er : NaY ( WO 4 ) 2 and Er : Yb : Ce : NaY ( WO 4 ) 2 crystals were grown by the Czochralski method. Er : Yb : NaY ( WO 4 ) 2 , Er : Ce : NaY ( WO 4 ) 2 , and Yb : NaY ( WO 4 ) 2 crystal powders were synthesized by means of the solid-state reaction. The spectroscopic properties of the crystals were investigated, including the absorption and fluorescence spectra and fluorescence decay. The energy transfer efficiency from Yb 3 + to Er 3 + in Er : Yb : NaY ( WO 4 ) 2 and Er : Yb : Ce : NaY ( WO 4 ) 2 was calculated and analyzed. End-pumped by a diode laser at 970 nm in a hemispherical cavity, a 1.84 W quasi-continuous-wave laser around 1.55 μ m with a slope efficiency of 17% and an absorbed pump threshold of 1.60 W was achieved in a 1.04 mm thick c-cut Er : Yb : Ce : NaY ( WO 4 ) 2 crystal. The results show that the Er : Yb : Ce : NaY ( WO 4 ) 2 crystal with high Ce 3 + doping is a candidate for gain medium of low threshold 1.55 μ m laser.
