E. Delre et al., 2-DIMENSIONAL PHOTOREFRACTIVE SPATIAL SOLITONS IN CENTROSYMMETRIC PARAELECTRIC POTASSIUM-LITHIUM-TANTALATE-NIOBATE, Applied physics letters, 73(1), 1998, pp. 16-18
We report the observation of steady-state two-dimensional photorefract
ive self-trapping and screening spatial soliton formation in a sample
of potassium-lithium-tantalate-niobate in the centrosymmetric paraelec
tric phase. (C) 1998 American Institute of Physics.
