“…Among oxide glasses, tellurite glasses have the advantages of good transparency in the mid-infrared (0.35-6 mm), high dielectric constants, good glass stability and Ln ion solubility. They have lower phonon energy (700-800 cm À1 ) and larger refractive index, compared to other oxide glasses (such as silicate, borate and phosphate), both of which are beneficial for high radiative transition rates of Ln ions [2,3]. Tellurite glasses could also be used in the production of optical fibers and planar waveguides.…”

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,
