摘要: Recent advances in the growth of ferroelectric crystals with low optical losses and good structural consistency particular KTiOPO 4 stoichiomethic Mg:LiTaO 3 allowed a vast extension applicability quasi-phase-matched frequency converters. In this paper we overview recent structuring these materials enabling high-energy pulse generation, extremely broadband parametric gain, some unique applications quasi phase-matched containing submicron-periodicity 1D structures as well 2D-structured crystals.
