摘要：
We report on backward second-harmonic-generation in bulk periodically poled congruent lithium niobate with a 3.2 mu m period. A tunable continuous-wave Ti:sapphire laser allowed us exciting two resonant quasi-phase-matching orders in the backward configuration. The resonances were also resolved by temperature tuning and interpolated with standard theory to extract relevant information on the sample.
