We describe an electronically tunable intracavity filter, based on the acoustooptic effect, that suppresses the sideband instabilities in a free electron laser. Different configurations are analyzed, and the problems encountered in the design and construction of a broadband acoustic transducer are discussed in some detail. In addition, some preliminary experimental results on the construction of broadband acoustic transducers are reported. The main advantages of this device are high damage threshold, low insertion losses, good tunability, and easy handling.
