title: Backward second-harmonic generation in periodically poled bulk LiNbO(3).
abstract: We experimentally demonstrate backward second-harmonic generation in periodically poled LiNbO(3) with a 3.3- microm domain period. We observed higher-order phase matching near 1490, 1600, and 1700 nm (fundamental) for the 19th, 18th, and 17th orders, respectively, with a maximum conversion efficiency of 0.02%.
