dc.description.abstractA high conversion efficiency in acousto-optical (AO) modulation can be obtained through careful design of an acousto-optic modulator (AOM), as well as careful selection of the following: the AO crystal material, the orientation in the AO crystal with respect to direction of propagation of the acoustic wave, the piezoelectric transducer material, the orientation of the transducer material, and the AOM fabrication method. A class of AOM's has been introduced wherein the diffraction efficiency of the AOM is improved by augmenting the design of the AOM so as to produce two or more passes of the optical beams through the acoustic beam wherein the Bragg diffraction conditions are satisfied. The effects of changes in acoustic beam direction and optical beam directions of propagation for the multiple-pass configuration are described in this dissertation. An AOM is fabricated in order to test the predicted properties of the class of AOM's incorporating the multiple-pass of optical beams for improving the conversion efficiency in AO modulation. Certain ones of the predicted properties of the multiple pass class of AOM's are confirmed by double pass experimental results for the fabricated AOM.
