Paper Abstract

A new acousto-optic tunable filter utilizing collinear acousto-optic interaction along the direction near to the optic axis is proposed and demonstrated by using LiNbO3 crystal. Using this near axis interaction lowers the driving acoustic frequency and also expands the angular aperture in the ordinary plane. The acousto-optic figure of merit M2(=n03ne3p2/pv3) of this filter is 7.5 x10-18 sec3/g, and tuning from 7000Å to 4200Å can be obtained by changing the acoustic frequency from 56MHz to 119MHz. At 5145Å, the filter bandwidth of 11 Å and the angular aperture of about 6° in the ordinary plane have been obtained.
