Enhanced emission in the NIR range by Nd3+ doped borosilicate glass for lasing applications
Borosilicate glasses were prepared via melt quench technique with different concentration of Nd3+ ions. X-ray diffraction (XRD) was performed for the prepared glass to study the amorphous structure. The glass stability was studied by Thermo-gravimetric Analysis (TGA). Spectroscopic analysis of the prepared glasses was done through absorption, excitation, emission and decay measurements. Absorption spectra was used to evaluate the J-O parameters. Radiative parameters are evaluated with the help of application of J-O theory. Emission spectra show three prominent bands in NIR region arising from 4F3/2 → 4I9/2, 4I11/2 and 4I13/2 centered around 910, 1068 and 1339 nm accordingly, with the most intense being the one at 1068 nm. Stimulated emission cross section, branching ratio and quantum efficiency for 4F3/2 → 4I11/2 transition is very high and is suitable for lasing applications. Dipole–dipole interaction is observed among activator ions on the basis of Dexter theory. The optimized Nd3+ doped glass (NBS10) possess maximum value for all radiative parameters and hence can be best suited for applications in the area of lasers and fiber amplifiers.
