چکیده انگلیسی
We report on the crystal growth, structure, room- and low-temperature (6Â K) absorption and emission spectroscopy of a 3Â at% Yb3+-doped trigonal ordered langasite-type silicate crystal, Ca3NbGa3Si2O14 (Yb: CNGS). The Rietveld refinement data are presented. Absorption, stimulated-emission and gain cross-sections are determined for the Yb3+ ion in CNGS for Ï and Ï polarizations. The maximum stimulated emission cross-section amounts to ÏSE = 0.97 Ã 10â20Â cmâ2 at 1014Â nm (Ï-polarization). The Stark splitting of the Yb3+ multiplets is resolved. Microchip laser operation is obtained with both a-cut and c-cut 3Â at% Yb: CNGS samples under end-pumping at 976Â nm by a Volume Bragg Grating-stabilized diode laser. For the latter cut, the maximum output power reaches 7.61Â W at 1048-1060Â nm with a slope efficiency of 59%. By varying the output coupling, multi-watt emission over a 50Â nm-broad spectral range is achieved.
