Abstract:

To increase concentration of Yb3+-ions in BaWO4 crystals, co-doped K+-ions method were adopted. Absorption coefficient of K+(x (K+) = 0.01), Yb3+ (x (Yb3+) = 0.02):BaWO4 crystals is α = 0.494 cm-1 at 977 nm. Fluorescence spectra of Yb3+-ions from 960 nm to 1020 nm, corresponding to transition 2F5/2 → 2F7/2 was investigated. Emission cross section at 1005 nm is 6.286 × 10-20cm2, livetime is 0.4 ms. The experimental result shows that K+, Yb3+:BaWO4 is a potential laser crystal.
