The influence of SiO 2 content on spectroscopic properties and laser emission efficiency of Yb 3+-Er 3+ co-doped calcium aluminosilicate glasses
Abstract:
We have studied the influence of SiO <inf>2</inf> content on the spectroscopic properties and laser emission efficiency of Yb <sup>3+</sup>- Er <sup>3+</sup> co-doped calcium aluminosilicate glasses. An increase in SiO <inf>2</inf> content resulted in higher phonon energy, which reduced the up-conversion emission, enhanced the energy transfer efficiency up to 70 % from Yb <sup>3+</sup> to Er <sup>3+</sup>, and enhanced the optical quality. All these results led to an increase from 20 to 30 % in the laser emission efficiency. © Springer-Verlag 2012.
