Abstract :
Summary form only given. MgO-doped LiNbO/sub 3/ (MgO:LN) has attracted much attention in quasi-phase-matched (QPM) wavelength conversion due to high resistance to photorefractive damage and low coercive field allowing a large aperture device. Since first measurement of the coercive field, the crystal has be- come popular in QPM application and recent works have been verifying high performance of the material. To improve device characteristics, characterization of the domain movement is required for a device with larger aperture. We report in-situ monitored poling process and coercive field dependence on Mg content in MgO:LN.
