The possibility of amplifying two frequencies simultaneously in a free electron laser is discussed. Stability conditions for electron motion are derived, and numerical calculations reported. The advantages offered by using a DC Pelletron beam to power such a device, with application to the plasma beatwave accelerator-high efficiency, high average power, radiation wavelength tunability, and the possibility of phase locking several independent optical cavities-are evaluated. Related research efforts, and their impact on the design of this device, are discussed. (10 References).
