Abstract
Raman confocal microscopy was applied for visualization of the ferroelectric domain structure in strontium barium niobate single crystals. The studied domain structure was produced by electric field poling of the single domain state at room temperature. Essential frequency shift of the certain Raman band in the vicinity of domain walls was revealed. Recording of this parameter during two-dimensional scanning was used for reconstruction of the domain images both at the surface and in the bulk.
