| Abstract: | Judd–Ofelt parameters (Ω2 = 5.09∙10–20, Ω4 = 0.92∙10–20, and Ω6 = 0.63∙10–20 cm2) and oscillator strengths of fundamental optical transitions involved in lasing at wavelength 1.54 μm have been calculated
for borosilicophosphate glass co-activated with Er3+ and Tb3+ ions based on experimental luminescence and absorption spectra and refractive indices. The results were used to determine
the emission (6∙10–23 cm2) and absorption (5∙10–21 cm2) cross sections for λ = 1.54 μm and the gain cross section as a function of inverse population levels. |
