Over the past fifteen years free-electron lasers have demonstrated their ability to operate over a wide range of the electromagnetic spectrum using a variety of electron accelerators. This paper reviews the performance of two FEL amplifiers which were driven by Linear Induction Accelerators (LIAs). The characteristics of the LIA are compatible with high peak power, single-pass FEL amplifiers. The first experiment which is discussed here operated in the microwave regime and demonstrated high gain and high extraction efficiency using a tapered wiggler field. In this experiment, we studied many of the basic properties of FELs such as harmonic generation, phase shift and spatial mode excitation. The second experiment operated in the infrared regime and demonstrated gain guiding of the optical signal and verified a novel method of electron beam transport through the wiggler.
