WebJun 2, 2003 · A structure for quasi-phase matching of large cross section using 5 mol % MgO-doped LiNbO3 (MgO:LN) crystal for high-power wavelength conversion was realized. We have found that the coercive field to invert polarization of the crystal reduces drastically with elevated temperature. The coercive field reduces to 1.2 kV/mm at 250 °C, which is … WebIn a QPM nonlinear wave mixing process, the phase mismatching is compensated by shifting the phase relative to each another among mixing waves over a coherent distance through inverting the sign of the nonlinear coefficient in nonlinear medium (such as “poling” to invert the crystal orientation for fabrication of Periodically Poled Lithium ...
