Effect of light beam deviation from Bragg angle on the intensity of light diffracted on acoustic wave

Pieszyński K.

Scientific Bulletin. Physics / Lodz University of Technology

2010

Vol. 31

63-73

The paper describes the influence of the effect of light beam deviation from Bragg angle on the intensity of light diffracted on acoustic wave. The analysis was based on the results of numerical calculations. The calculations were made for several characteristic cases.

W pracy opisano wpływ odchylenia wiązki światła od kąta Bragga na natężenie ugiętego światła na fali akustycznej. Analizy dokonano w oparciu o wyniki obliczeń numerycznych. Obliczeń dokonano dla kilku charakterystycznych przypadków.

Light diffraction in an inhomogeneousacoustic field

Balakshy V., Linde B., Vostrikova A.

Molecular and Quantum Acoustics

2006

Vol. 27

7-16

Light diffraction in acoustic fields created by wedge-shaped and parabolic piezoelectric transducers is theoretically investigated. It is shown that the acoustic fields have a complicated amplitude-phase structure changing with the acoustic frequency. Principal characteristics of acousto-optic interaction are examined. It is demonstrated that the diffraction efficiency in the Bragg regime can approach 100% in spite of a noticeable phase mismatch.
