摘要: Thermal poling of silica glass modified by femtosecond laser irradiation is demonstrated. Increase second-harmonic generation in the irradiated regions observed. This enhancement interpreted terms structural modifications that make process more efficient. Evidence a change distribution electrostatic field frozen during obtained. technique used for χ(2) grating fabrication.
