Laser spectroscopy of Nd3+-doped PbO–Bi2O3–Ga2O3–BaO glasses

Luminescence characteristics of Nd3+-doped K–Ba–Al-fluorophosphate laser glasses

“…1(a) and (b), respectively. The band positions in these spectra closely resemble to those reported in earlier works on systems such as Nd 3+ : phosphate and fluorophosphate [4][5][6], Nd 3+ : fluorozincate [7] and Nd 3+ : lead based oxide [8][9][10] glasses except some slight variations in their relative positions, broadening and intensities due to changes of chemical environment around the Nd 3+ ions.…”

Spectroscopic investigations of 1.06μm emission in Nd3+-doped alkali niobium zinc tellurite glasses

“…As seen in Table 3, all these parameters were well within the ranges commonly reported for Nd 3 + -doped laser glasses [6][7][8][19][20][21][22][23][24][25][26].…”

“…As seen in Table 2 , which is known as spectroscopic quality factor, w. If w is smaller than unity, the intensity of the 4 F 3/2 -4 I 11/2 transition is stronger than that of the 4 F 3/2 -4 I 9/2 transition in that host. The w value for TZNLN glass is found to be 0.88 which is comparable to other oxide glasses including commercial laser glasses [23,24,26,28]. From the w values listed in Table 2, it can be predicted that the intensity of 4 F 3/2 -4 I 11/2 transition in the TZNLN glass will be larger than that of the 4 F 3/2 -4 I 9/2 transition which is similar to the TeO 2 -Na 2 O glass [22].…”

XRD and FTIR structural investigations of erbium-doped bismuth–lead–silver glasses and glass ceramics

“…Thus, it can say that the increase of the erbium oxide content decline the presence of BiO 6 and PbO 3 The structural changes observed by varying the Er 2 O 3 concentration of xEr 2 O 3 (100 − x)[72Bi 2 O 3 ·25PbO·3Ag 2 O] systems, as suggested by the FTIR investigation, shows that the erbium ions play a network modifier role in these glass and glass ceramic systems.…”

“…Due to these properties, the use of the mentioned glasses provides the possibility of developing more efficient lasers and fiber optic amplifiers [3][4][5][6]. Despite the fact that Bi 2 O 3 is not a classical glass former, due to the high polarizability of the Bi 3+ ions, in the presence of other glass formers such as B 2 O 3 [7], PbO [8][9][10], V 2 O 5 [11] or of some alkali oxides (i.e., lithium oxide) [12], it may build up a glass network.…”
