Abstract: The technology disclosed relates to developing an acousto-optic device (AOD) using an alpha-barium borate (?BBO) crystal. An AOD using ?BBO enables high-resolution microlithographic patterning. The AOD includes a slab of ?BBO coupled to an RF transducer that drives an acoustic wave through the crystal structure. A laser source emits a beam of light that is incident on the crystal surface. The propagated acoustic wave acts as a diffraction grating that diffracts the incident wave. Using an ?BBO crystal allows for high resolution of light in the ultraviolet and visible spectra. The low speed of acoustic wave propagation through the crystal allows for more laser spots to be imaged than AODs made using other types of crystals.
