Description
Full text: The 4I13/2 to 4I15/2 laser transition in Er3+ ions at 1.5 - 1.6 μm has wide applications in telecommunications, eye-safe laser ranging and LIDAR systems. From an energy transfer analysis of a 2 at. % Er, 20 at. % Yb doped YCOB crystal, we have determined a dipole-dipole transfer coefficient of WDAd-d = 6.1 x 103 s-1 which compares favourably with alternative laser hosts, and a transfer efficiency of ηET ∼ 90 %. These results indicate that Er-Yb:YCOB is a very promising material which should provide much more efficient laser performance compared with other Er-Yb laser crystals and glasses
