Abstract

Recent advances in the growth of ferroelectric crystals with low optical losses and good structural consistency in particular KTiOPO₄ and stoichiomethic Mg:LiTaO₃ allowed a vast extension of applicability of quasi-phase-matched frequency converters. In this paper we overview recent advances in structuring these materials enabling high-energy pulse generation, extremely broadband parametric gain, and some unique applications in the quasi phase-matched crystals containing submicron-periodicity 1D structures as well as in 2D-structured crystals.
