Abstract:We consider simultaneous diffractions of light by two lobes of sound radiation pattern in an acousto-optic modulator which is built on SiO 2 single crystal and has two-element phased-array transducer with the fixed phase shift .Implementation of this diffraction type greatly improves power efficiency of the device. Transducer shaping is used to steer the lobes and satisfy the Bragg's conditions for simultaneous acousto-optic diffractions. The conditions of the diffraction are defined and a mathematical model… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
