The third‐order nonlinear optical susceptibilities, X (3) , of TeO 2 ‐based glasses containing transition metal oxides (M = Sc 2 O 3 , TiO 2 , V 2 O 5 , Nb 2 O 5 , MoO 3 , Ta 2 O 5 , and WO 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 2 , Nb 2 O 5 , and WO 3 to TeO 2 glass increases the X (3) value as well as the refractive index, while others decrease both of them. The positive effect of the TiO 2 , Nb 2 O 5 , or WO 3 , on the X (3) of TeO 2 glass was interpreted in terms of the cationic empty d ‐orbital contribution. There is an almost linear relation between the X (3) and the term ( n 2 ω + 2) 3 .( n 2 ω ‐1). E d / E 2 0 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 X (3) value obtained is 1.69 × 10 −12 esu for 30NbO 2.5 .70TeO 2 glass, about 60 times larger than that of pure fused silica glass.
