Recent advances in ultra short laser systems have led to the development of new charged particle acceleration techniques. Such techniques could enable the construction of very compact accelerator-based short-wavelength coherent radiation sources. A recently proposed concept involves using a laser to directly accelerate an electron beam and scatter the produced beam to generate X-rays. This can be done within a one meter footprint. The purpose of this work is to explore the condition for extending this process, known as inverse Compton scattering (ICS), into the coherent regime. Our approach includes the modification of an electrodynamics program developed at MIT and the numerical study of far field radiation from first principles. With these programs, we were able to show that practical requirements were more demanding than previously thought.
