The frequency of the radiation scales quadratically with the energy of the electrons. Conventional RF accelerators have limited accelerating gradients that make reaching electron energies capable of producing hard X-rays a dicult engineering demand that requires hundreds of meters of linac sections. Next generation light sources aim to compactify the current sources by employing high gradient advanced accelerators and very short period undulators. Small footprint, narrow bandwidth X-ray sources can have a large impact on X-ray science and its applications ranging from the medical eld to material science to the interrogation of the nuclear structure of matter. In this dissertation, two approaches to the scaling down of X-ray sources are taken up. The performance of a free electron laser (FEL) based on sub-mm period undulators is studied on theoretical grounds. The experimental realization of an all-optical scheme is demonstrated. The output electron beam of an inverse free electron laser (IFEL) accelerator, driven by a terawatt CO2 laser, is fed into an inverse Compton scattering (ICS) collision with a retro-reflected CO2 laser pulse
