$Spatial harmonics of photorefractive gratings in a barium titanate crystal$

Spatial harmonics of photorefractive gratings in a barium titanate crystal

Calibrated optical Bragg-scattering measurements of the fundamental steady-state space-charge-field amplitude, and of two higher spatial harmonics, in photorefractive p-type barium titanate excited by a light intensity pattern that is a simple sine function of distance are reported. These measuremen...

Beschreibung
Zusammenfassung:	Calibrated optical Bragg-scattering measurements of the fundamental steady-state space-charge-field amplitude, and of two higher spatial harmonics, in photorefractive p-type barium titanate excited by a light intensity pattern that is a simple sine function of distance are reported. These measurements are performed over the entire range (0
