MgO:LiNbO3(Magnesium oxide doped lithium niobate) – Nonlinear Crystal – Customized Products

MgO-doped LiNbO3 nonlinear crystals have high optical damage threshold and high nonlinear conversion efficiency than undoped LiNbO3 crystals, and the doping can lead to increased Raman scattering cross section and reduced phonon mode loss. MgO: LiNbO3 nonlinear crystals have unique advantages over LiNbO3 nonlinear crystals for NCPM multiplication, mixing and optical parametric oscillation in Nd-doped lasers. crystals are widely used in optical parametric oscillation (OPO), optical parametric amplification (OPA), quasi-phase matching, and integrated optical waveguides.
