crystal is reported for the first time. The coercive field of the crystal was found to be ~1.2kV/mm
only a twentieth of that of the congruent LiNbO

. Homogeneous domain patterns with periods of 6.2~6.4μm was used for the second harmonic generation of green light. A normalized second harmonic generation efficiency 4.8%/W was obtained at room temperature.
