Abstract

Summary form only given. Tellurium dioxide (TeO/sub 2/) is a very popular crystal as an interaction medium for acousto-optic tunable filters (AOTFs) in both visible and IR. This is due to its high birefringence and figure-of-merit for slow shear wave propagating closely to <110> direction. However there are intrinsic drawbacks associated with the TeO/sub 2/ crystal, which prevent a conventionally designed noncollinear AOTF from achieving subnanometer spectral resolution with a reasonable optical aperture, which are necessary for many electroscopic applications, such as Raman. This paper presents a newly designed TeO/sub 2/ filter which overcomes these drawbacks.
