説明
<jats:p>A power second-harmonic generation (SHG) study has been carried out on (K2O)15(Nb2O5)15(TeO2)70 glass ceramic, which consists of centrosymmetric crystals embedded in a centrosymmetric glass matrix. The effective second-order nonlinear optical coefficient, χ(2), of this material at 532nm is found to be 1.3pm∕V or approximately ten times that of quartz, leading to a maximum second-harmonic intensity approximately 100 times that of quartz. This material is nonphase matchable, with a coherence length of 30μm. We conclude that the SHG in this material originates from the abrupt changes in optical susceptibility at the interfaces between the glass and crystal, together with the higher-order nonlinear response.</jats:p>
