Abstract
Second‐harmonic generation has been observed in poled 10Li2O10Na2O80TeO2 glass. The effect of poling temperature on the second‐harmonic intensity has been examined. The second‐harmonic intensity increases, attains a maximum, and then decreases as the poling temperature increases. In other words, an optimum poling temperature that results in a maximum second‐harmonic intensity exists. The optimum poling temperature linearly increases as the glass‐transition temperature increases for several types of tellurite glasses, including the present 10Li2O10Na2O80TeO2 glass. This fact suggests that the process to create a polarization that results in the second‐harmonic generation is affected by the structural relaxation at the glass‐transition range. The thermal stability of 10Li2O10Na2O80TeO2 glass is higher than that of 18Na2O82TeO2 (30NaO1/270TeO2) glass, as revealed via differential scanning calorimetry. As a result, the temperature range within which the poling is effective is wider for the former glass.
