Nonlinear optical properties of TeO{sub 2}-based glasses: MO{sub x}-TeO{sub 2} (M = Sc, Ti, V, Nb, Mo, Ta, and W) binary glasses
- Kyoto Univ. (Japan). Inst. for Chemical Research
The third-order nonlinear optical susceptibilities, {chi}{sup (3)}, of TeO{sub 2}-based glasses containing transition metal oxides (M = Sc{sub 2}O{sub 3}, TiO{sub 2}, V{sub 2}O{sub 5}, Nb{sub 2}O{sub 5}, MoO{sub 3}, Ta{sub 2}O{sub 5}, and WO{sub 3}) glasses have been measured by the third harmonic generation (THG) method in order to investigate the effect of the empty d-orbital contributions to the third-order nonlinear optical susceptibilities. It is found that the addition of TiO{sub 2}, Nb{sub 2}O{sub 5}, and WO{sub 3} to TeO{sub 2} glass increases the {chi}{sup (3)} value as well as the refractive index, while others decrease both of them. The positive effect of the TiO{sub 2}, Nb{sub 2}O{sub 5}, or WO{sub 3}, on the {chi}{sup (3)} of TeO{sub 2} glass was interpreted in terms of the cationic empty d-orbital contribution. There is an almost linear relation between the {chi}{sup (3)} and the term (n{sub {omega}}{sup 2} + 2){sup 3}{center_dot}(n{sub {omega}}{sup 2}{minus}1){center_dot}E{sub d}/E{sub 0}{sup 2} containing three measurable parameters only, irrespective of the kinds of MO, which was derived based on the bond orbital theory developed by M. E. Lines. The largest {chi}{sup (3)} value obtained is 1.69 {times} 10{sup {minus}12} esu for 30NbO{sub 2.5}{center_dot}70TeO{sub 2} glass, about 60 times larger than that of pure fused silica glass.
