| Abstract: | Measurements of two-photon absorption (TPA) coefficients β at 532 nm in binary Bi2O3:B2O3 glasses are reported. The β obtained ranges from 12.9 to 16.4 cm/GW with the larger value observed in higher Bi2O3 glass. The relationship between β and glass composition is discussed in terms of the electronic structure of glasses: β can be scaled with optical band gap. |
