| Abstract(in English) | We have demonstrated large second-order optical nonlinearity is generated in thermally poled high-purity silica glass that is exposed to KrF excimer laser pulses before the poling. The maximum χ_<33>^<(2)> value is 0.71pm/V in the sample annealed to 900℃ in air, namely introduced to O_2 molecules. A further interesting point is that KrF excimer laser pulses erase the nonlinearity induced in the glasses too. Based on the detailed studies on the laser irradiation effects on the generation an erasure processes, and also optical absorption and luminescence, we show that point defects of ≡Si-O^- play a key role for the nonlinearity formation in the poled high-purity sihca glass. |
