- Abstract
Yb3+-doped silicate glasses (SiO2-Nb2O5-K2O-ZnF2) were prepared by a conventional melt quenching technique and their spectroscopic properties were investigated. The emission cross-section was found to be 0.53 × 10-20 cm² at 1006 nm from the reciprocity method described by McCumber from the measured absorption spectrum of 1.0 mol% Yb2O3-doped glass. The lifetime (τexp) and figure of merit (σem × τexp) for the ²F5/2 → ²F7/2 transition of 1.0 mol% Yb2O3 -doped silicate glass, were evaluated to be 0.50 ms and 0.26 cm² ms, respectively. The other spectroscopic parameters, βmin, Isat and Imin were found to be 0.17, 29.00 kW/cm² and 4.90 kW/cm², respectively. The results indicate that the present Yb3+-doped silicate glasses could be useful as laser gain media at 1006 nm.
