Neodymium-doped magnesium phosphate glasses for NIR laser applications at 1.05 μm

Optical properties investigation and multicolor behavior of neodymium (Nd3+)‐doped oxyfluoride silicate glasses SiO2‐PbO‐PbF2

“…There is no rule of net change for these two parameters; their values remain within a certain range. The trend of JO intensity parameters for Nd 3+ in SiO 2 -PbO-PbF 2 is Ω 6 > Ω 4 > Ω 2 , which is quite similar to the patterns that have been reported for Nd 3+ in other glass matrices[14,[41][42][43][44]. The spectroscopic quality factor χ = Ω 4 /Ω 6 , introduced by Kaminskii and widely F I G U R E 5 Energy levels diagram of SiO 2 -PbO-PbF 2 : Nd 3+ (1 mol%).…”

“…In the literature, the authors estimate this error to be between 5% and 25%, and others even suggest an error of 30% in the case of the JO calculation [40, 45]. In this work, the JO parameters are obtained with an quality of adjustment equal to $$$ \delta =\pm 0.167\times {10}^{-20}{\mathrm{cm}}^2 $$$ reflecting the calculation's accuracy and the best agreement with values found in other host matrices [41–44, 46].…”

Luminescence and Gamma Spectroscopy of Phosphate Glass Doped with Nd3+/Yb3+ and Their Multifunctional Applications

“…The branching ratios of 4 F 3/2 → 4 I 9/2 and 4 F 3/2 → 4 I 11/2 transition in the PZLBNdYb glass was ~41% and 48%, respectively, which is comparable to BSKNLNd10 and PNbKA [36,37], PZLNNd1.0 [38], phosphate [14] and Nd 3+ -doped P 2 O 5 -Li 2 O 3 -GdF 3 [29] glasses (see Table 4).…”

Optical spectroscopy as a tool for studying the solution chemistry of neodymium(iii)

“…118,131,132 Many modern laser materials have low symmetry for this reason. 133,134 The largest remaining issue in neodymium(III) laser media is the heat accumulation. A recurring suggestion is to move to liquid lasers, 45,110,112,135 but the other advantages of solid state lasers make them dominate the market.…”
