Structural and spectroscopic characterization of cadmium sodium phosphate glasses doped with ytterbium for optical applications

Cadmium sodium phosphate glasses doped with ytterbium ions were fabricated by standard melt-quenching technique. The structural changes of the glass matrix doped with different ratios of Yb3+ ions were investigated via FTIR and Raman spectroscopies. The optical absorption spectra were studied via UV-Vis-NIR spectroscopy and the optical constants such as bandgaps, Urbach energies, refractive indices, and dispersion parameters were calculated. The emission cross-sections and gain spectra for F-2(5/2). F-2(7/2) transition of Yb3+ ions were investigated. The high values of emission cross-sections of the studied glasses make them strong candidates for laser and amplifier applications.

Automated summary

Cadmium sodium phosphate glasses doped with ytterbium ions were investigated in terms of their structural changes, optical absorption spectra, emission cross-sections, and gain spectra for laser and amplifier applications.
