Abstract
An infrared tunable acousto-optic filter based on Tl3AsSe3 in a noncollinear configuration is described. The filter was operated at CO2 laser wavelengths from 10.8 to 9.3 μm, with corresponding rf drive frequencies in the 15–18-MHz range. Filter bandwidths are of the order of 20–30 cm−1, and the measured tuning rate is 18.0 kHz/cm−1 at 10 μm.Keywords
