摘要：

We observe dynamic ferroelectric domain gratings in strontium barium niobate (SBN) induced by photorefractive space charge fields. The optically induced modulation of the spontaneous polarization attains a maximum of 1%. Quasi-phase matched second harmonic enhancements are observed above the ferroelectric-paraelectric phase transition due to the glassy ferroelectric nature of SBN. We find that the second harmonic power is significantly enhanced by recording gratings in optically fatigued rather than electrically poled crystals.© 1995 American Institute of Physics.
