Quantitative decay measurement of the second-harmonic generation (SHG) at various elevated temperatures is reported for a GeO2-SiO2 glass with 15.7 GeO2 mole %, poled with UV-irradiation. It has been observed that the decay behaviour of the induced SHG is a single-exponential process in the temperature range 200-500°C. From the Arrhenius plot of the decay timeconstant, the activation energy of the induced SHG is 0.41 ± 0.05eV, and the decay time-constant at 15°C is ∼280 days.
