“…Judd-Ofelt parameters of several Nd 3+ doped glasses for hypersensitive transition given in Table 2. There is one material [28] shown that intensity parameters  2 < 2, this condition represent the high covalent bonding that means there was broadening asymmetry around the environments glass [18]. Table 2 showed generally was observed that  2 >  4,6 [2,20,30,31,31,33] indicate the higher covalency of the ion-ligand bond lower symmetry of the Nd 3+ ion site.…”

“…Moreover, the borate glass properties have been reported as well high transparency, high density, appropriate bandwidth, suitable for infrared transmission, high mechanical stability, corrosion resistivity and inexpensive [2,15]. In addition, the other types of glasses and crystals have been reported as well as a host of Nd 3+ ion laser such as Nd 3+ doped alkali niobium zinc tellurite glasses [16], Nd 3+ doped barium titanium silicate glasses [17], Nd 3+ ions in fluoro-phosphate glasses [18], Nd 3+ doped lanthanum calcium borate glasses [19] and Nd 3+ doped alkali boro germanate glasses [20]. In this paper discussed some of the parameters needed in the determination of the glass composition doped Nd 3+ ion to be used as a laser gain medium.…”

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,

“…As for optoelectronic applications of phosphate glasses, these are considered promising due to their high solubility and stimulated emission cross-section of rare-earth ions [1,[16][17][18][19][20].

“…Er 3+ -doped phosphate optical fiber [21] and waveguides [18] have already been demonstrated, thus proving their potential as photonic materials. Recently, modification of phosphate glass structures has been tried not only to improve the chemical stability of phosphate glass but also to enhance the quantum efficiency of rare-earth dopants; some instances include the formation of nanocrystals of rare-earth phosphate [16] and the introduction of fluoride or chloride phases into a phosphate host matrix [19,20].…”
