摘要: We prepared nonresonant-type homogeneous glasses containing Bi2O3 by the melting method. The third-order optical nonlinear susceptibility χ(3) was found harmonic generation measurement to be 9.3 × 10−12 esu. attribute nonlinearity of these large molar refraction Bi2O3. These also exhibited an ultrafast response time below 200 fs a degenerate four-wave mixing method using femtosecond laser, indicating that originated mainly from pure electronic polarization.
