“…According to other authors, the 4 I 9/2 ? 4 G 5/2 , 2 G 7/2 hypersensitive transition at 585 nm (17,100 cm À1 ) is the most intense one, as can be observed in other tellurites, fluorophosphates and bismuth borated glasses [5,6,13,34], and are governed by the quadrupole selection rules ðjDSj 6 0; jDLj; jDJj 6 2Þ [35,21].…”

“…Among the common requirements that must fulfill the glasses hosts highlight wide transmission ranges from ultraviolet (UV) to mid-infrared (IR), good chemical, mechanical and thermal stabilities, high nonlinear refractive index, and relatively low-energy phonon, which reduce the multiphonon non-radiative probabilities and, consequently, increase the quantum yields. In this regard, glasses such as chalcogenides, borates, fluorozirconates, fluorides, silicates [4][5][6] and tellurites have been the subject of several extensive studies.…”

“…Nevertheless, for suitable applications in ultra-fast spectroscopic investigations and non-heating laser processing it is necessary to develop highaverage power, high-efficiency, compacts and low-cost femtosecond lasers. In this regard, the transitions at 4 ($1340 nm) in the NIR-range are the most suitable for the commented applications [6]. We will focus on the more intense band corresponding to the 4 F 3/2 ?…”

“…4 I 11/2 transition. Several results have been reported on the luminescent properties of Nd 3+ ions in a variety of glass matrices which include silicates [14], borates [6], tellurites [15] and chalocogenides [16]. Thus, the luminescent properties of the Nd 3+ ions are considerably modified by suitably selecting the network of the forming and the modifying cations.…”

a b s t r a c tA study of the optical properties of Nd 3+ ion in TeO 2 -PbF 2 -AlF 3 glasses has been carried out for different Nd 3+ concentrations. Based on the Judd-Ofelt theory, intensity parameters and radiative properties were determined from the absorption spectra. Focusing on the suitability of this host for laser applications, the spectroscopic quality factor v was obtained with a value of 1.07, a value of the order of other compositions proposed as laser hosts. For the most intense emission corresponding with the 4 F 3/2 ? 4 I 11/2 transition (1.06 lm), the absorption and emission and have been calculated with values of 1.20 Â 10 À20 cm 2 , 2.08 Â 10 À20 cm 2 . A positive value for the gain cross-sections has been found for a population inversion factor c of 0.4 in the spectral range from 1060 to 1110 nm. All these results suggest the potentially use of this system as a laser host.

“…In addition, the intensity of the absorption peak of hypersensitivity split was also caused by changes in the content of the composition glass. On the other hand, some medium glasses have the same absorption peak, which splits disappearances have occurred by expansion of homogeneity [33]. The oscillator strength values are strongly influenced by the type and composition of other metal compounds as modifiers of the glass network structure.…”

Radiative properties and spectroscopic studies of several Nd 3+ doped borate glass system have been reported. Judd-Ofelt intensity parameter and other parameters like oscillator strength (f), effective bandwidth ( eff ), radiative transition probabilities (A R ), stimulated emission cross section (), branching ratio ( R ), radiative lifetime ( R ) and experimental lifetime ( exp ) for the hypersensitive Nd 3+ doped Borate Glass are listed and discussed. The variation of  2 values for the different host matrix are expressed their covalency among Nd 3+ ions in the glass matrix. In this study, reported that the hypersensitive transition achieved at 4 I 9/2  4 G 5/2 , 2 G 7/2 centered at 580 -585 nm range.Keywords: Borate glass, Judd-Ofelt, radiative INTRODUCTIONIn the several years and recently, laser gain medium based on Nd 3+ doped glasses have been attracted much attention from researchers in the field of photonic and laser. The above related to Nd 3+ laser application such as optical amplifier, laser pumping, optical communication, optical waveguide, storage data optically, radar and medical instrumentation [1][2][3][4][5]. Medium gain laser characteristics for commercial laser required were must satisfied sharpness fluorescent lines, strong absorption bands and sensible for high quantum efficiency in accordance with the needed transition photon [6].The above requirements have been obtained by a small amount of concentration Nd 3+ ions-doped glass material, since Nd 3+ ions were able to produce population inversion for result stimulated emission in the visible range (such as emission transition at 4 G 7/2  4 I 9/2 , 4 G 7/2  4 I 11/2 , 4 G 7/2  4 I 13/2 ) [7] and the NIR range (lasing transition 4 F 3/2  4 I 9/2 , 4 F 3/2  4 I 11/2 , 4 F 3/2  4 I 13/2 ) [1]. Improved laser performance is strongly influenced by the composition of the host glass matrix and the concentration of doped ions, since the stimulated emission quality depends on host matrix in which the ions are incorporated [7,8]. Several types of commercial glass are generally used as a laser host matrix, i.e silicate, phosphate, borate glasses and several heavy metal oxide glasses [1,2,7,9]. Some of the results showed that the silicate glasses has its advantages as well as high chemical stability, high transparency for UV, low thermal expansion coefficient leading to strong thermal resistance, a small nonlinear refractive index, high surface damage threshold,

The spectroscopic properties of Tellurium Calcium Zinc Niobium oxide Borate (TCZNB) glasses of composition (in mol%) 10TeO + 15CaO + 5ZnO + 10 Nb O + (60 - x)B O + Nd O (x = 0.1, 0.5, 1.0 or 1.5 mol%) have been investigated experimentally. The three phenomenological intensity parameters Ω , Ω Ω have been calculated using the Judd-Ofelt theory and in turn radiative properties such as radiative transition probabilities, emission cross-sections, branching ratios and radiative lifetimes have been estimated. The trend found in the JO intensity parameter is Ω > Ω > Ω If Ω > Ω , the glass system is favourable for the laser emission F → I in the infrared (IR) wavelength. The experimental values of branching ratio of F → I transition indicate favourable lasing action with low threshold power. The evaluated total radiative transition probabilities (A ), stimulated emission cross-section (σ ) and gain bandwidth parameters (σ × Δλ ) were compared with earlier reports. An energy level analysis has been carried out considering the experimental energy positions of the absorption and emission bands.
