Abstract: Abstract In acousto-optic imaging, the ultrasound-induced optical phase modulation has been widely used in the imaging of biological tissue. However, in Raman-Nath diffraction, the phase of diffracted light has not attracted much attention. Additionally, each… read more here.

Abstract: This paper analyzes the ultrasonic modulation of coherent light in Raman–Nath acousto-optic diffraction. We find that the frequency shifts of the diffracted light cause the periodic variation of the ultrasound-modulated light intensity with time. Additionally,… read more here.

DOI: 10.1364/ol.43.003168
Abstract: In this Letter, we studied the near-field effect of the nonlinear Raman-Nath diffraction experimentally in a 1D periodically poled LiTaO3 crystal and established a theoretical relationship between the nonlinear effect in the near field and… read more here.
