摘要：

Second harmonic generation has been observed in electrically poled tellurite glasses with 80TeO2 . 10Li2O . 10 Nb2O5 and 70TeO2 . 15Li2O . 15Nb2O5 compositions. The poling was carried out at 200 to 300-degrees-C for 30 min under applied dc field of 4 to 5 kV. To explain the mechanism generating the second-order nonlinearity in the poled tellurite glasses, it is proposed that strong local polarization is caused by migration of lithium ions and/or periodic orientation of lone pairs of electrons in the tellurium ions.
