摘要A series of GeO2 modified Yb: phosphate glasses were studied, covering thermal, optical, and fluorescence properties relevant to lasing performance. The host phosphate glass modified by introducing a second glass former, GeO2, was shown to have improved thermal stability, i.e., higher glass transition temperature (T-g) and lower coefficient of thermal expansion (CTE). Enlargement of Yb3+ E-2(7/2): Stark splitting, broadening of effective fluorescence linewidth (Delta lambda(eff)) and longer fluorescent lifetime (if) were also achieved at the same time, whereas emission cross section (Gem) of the modified glasses were kept nearly constant. Selective laser experiments were performed; while the baseline host phosphate glass failed in lasing, a GeO2-modified phosphate glass was able to deliver 370 mW laser output at 1063 nm. Significant improvement of the lasing performance was further demonstrated using a newly designed GeO2-modified Yb: phosphate glass based on our study, which demonstrated 724 mW laser output at 1063 nm. The overall results from our study showed that germanium phosphate glass system can be developed as a promising material for high energy, large scale Yb3+ laser.
