An overview of the design parameters of a compact high-gradient high-luminosity X-band (8.568 GHz) photoinjector is followed by a more detailed description of each of its major subsystems: X-band RF gun, GHz repetition rate synchronously modelocked AlGaAs quantum well laser oscillator, and eight-pass Ti:Al{sub 2}O{sub 3} chirped pulse laser amplifier. The photoinjector uses a high quantum efficiency Cs{sub 2}Te photocathode, and is capable of producing high-charge relativistic ultrashort electron bunches at 2.142-GHz repetition rate in burst mode. Design studies indicate that a normalized rms transverse emittance {var_epsilon}{sub n} = 0.75 {pi} mm-mrad is possible at 0.1 nC charge, while 2.5 {pi} mm-mrad is obtained at 1 nC. One of the most interesting applications of the photoinjector, namely the generation of ultrashort pulses of coherent synchrotron radiation, is then addressed in detail.
