Acousto-optic diffraction in biaxial crystals possessing considerable optic dispersion
- 44 Downloads
Influence of optic wavelength dispersion on phase matching conditions of acousto-optic interaction in optically biaxial media is considered for the first time. Diffraction of light by ultrasound is examined in basic optical plane of a biaxial crystal by the example of monoclinic double lead molybdate single crystal (Pb2MoO5). Frequency dependences of Bragg angle have been analysed taking into account wavelength dispersion of light. It is shown that a considerable transformation of the characteristics of the acousto-optic interaction is caused by a change of the directions of optic and dielectric axes in a biaxial medium with a tuning of optic wavelength.
