A large amplitude ion acoustic wave has potential as a wiggler to produce short wavelength coherent electromagnetic radiation in a free electron laser (FEL). The frequency of radiation is given as {omega}{sub 1} {approx_equal} 2{gamma}{sub 0}{sup 2}({omega}{sub 0}/c{sub s})v{sub b}cos{theta}{sub 0}, where {gamma}{sub 0} is the frequency of the ion acoustic wave propagating at angle {theta}{sub 0} with the electron beam and c{sub s} is the sound speed. The growth time of the instability at 10 {micro}m turns out to be in the submicrosecond range at beam voltage {approximately}1 MV and beam current {approx}1.5 A.
