    Acousto-optic tunable filters are useful for selecting specific wavelengths for excitation light in confocal and multiphoton fluorescence microscopy. The filter operates by establishing a radio-frequency standing acoustical wave in an appropriate crystal and creating, in effect, a bulk transmission diffraction grating.

    In this paperwe present a method for calculating the acoustic velocity and acousto-optic figure of merit (AOFM). The AOFM as a function of material's refractive index, density, effective elasto-optic coefficient and the velocity of the acoustic wave in the material, are also investigated. By examining the directional dependent velocity, elasto-optic coefficients, and refractive index,

  • Fiber-Q Fiber Coupled Modulators G&H

    As a byproduct of the acousto-optic effect, light passing through the 1st order diffraction mode of a fiber-coupled modulator also experiences a frequency shift and beam deflection. This allows our Fiber-Q ® products to be used for more than just modulation, resulting in applications outside the laser such as optical heterodyne interferometry.

  • Acousto Optic Principles

    ACOUSTO-OPTIC PHYSICAL PRINCIPLES MAIN EQUATIONS. An RF signal applied to a piezo-electric transducer, bonded to a suitable crystal, will generate an acoustic wave. This acts like a “phase grating”, traveling through the crystal at the acoustic velocity of the material and with an acoustic wavelength dependent on the frequency of the RF

  • OSA Acousto-optic control of internal acoustic

    Peculiar cases of acoustic wave propagation and reflection may be observed in strongly anisotropic acousto-optical crystals. A tellurium dioxide crystal serves as a prime example of such media, since it possesses record indexes of acoustic anisotropy. We studied one of the unusual scenarios of acoustic incidence and reflection from a free crystal-vacuum boundary in paratellurite.
