We present a theoretical model for the generation of coherent gamma
rays by a free electron laser, where a high-energy electron beam interacts with an
electromagnetic wiggler. By replacing the static undulator with a 1-μm laser wiggler,
the resulting radiation would go from X-rays currently observed in experiments,
to gamma rays. Coherent light in the gamma-ray range would have wide-ranging
applications in the probing of matter on sub-atomic scales.
