摘要：

The scattering cone (approximately 2-degrees) from an Ar laser beam (514 nm) in photorefractive KNbO3:Fe has been observed to transform into a reconfigurable hexagonal spot array. This phenomenon can be explained through the creation of laser-induced transmission and reflection grating arrays.
