Abstract :
A new type of acoustooptic tunable filter using noncollinear interaction in TeO2has been fabricated. Dynamic bandwidth of the filter is in the range between 0.42 and 0.75 µm and corresponding acoustic frequency is between 85 and 40 MHz. Efficiency up to 90 percent is obtained at the electrical power input of 50-400 mW and resolution of 12-25 Å is attained experimentally.
