Recent progress in accelerator physics and laser technology have enabled the development of a new class of gamma-ray light sources based on Compton scattering between a high-brightness, relativistic electron beam and a high intensity laser pulse produced via chirped-pulse amplification (CPA). In this talk, the current state-of-the-art will be reviewed, along with important applications, including nuclear resonance fluorescence. The design of a precision gamma-ray source will also be discussed, along with the key technologies chosen for the project: X-band linac and photo-injector, photo-cathode laser pulse shaping, and hyper-dispersion CPA.
