    Bright spatially coherent synchrotron X-rays from a table-top source

    Betratron oscillations of electrons driven through a plasma by a high-intensity laser generate coherent X-rays. A new study demonstrates the intensity of these X-rays can be as bright as that generated by conv...

    Energy scaling of quasi-monoenergetic electron beams from laser wakefields driven by 40-TW ultra-short pulses

    By focusing 40-TW, 30-fs laser pulses to the peak intensity of 1019 W/cm2 onto a supersonic He gas jet, we generate quasi-monoenergetic electron beams for plasma density in the specific range 1.5×1019 cm-3≤ne≤3.5...

    Holographic Snapshots of Laser Wakefields

    We report the first single-shot measurements of transverse and longitudinal structure of laser-generated wakefields. Real-time, non-averaged measurements of resonant wakes reveal detailed temporal and spatial ...

    Characterization of focal field formed by a large numerical aperture paraboloidal mirror and generation of ultra-high intensity (1022 W/cm2)

    We describe a method to measure the aberrations of a high numerical aperture off-axis paraboloid and correct for the aberrations using adaptive optics. It is then shown that the characterized aberrations can b...

    Generation, Amplitude and Phase Characterization of 1021W/cm2 Intensity

    The problem of intensity measurement at high-field regime is examined. We propose a method based on wave-front measurement that can evaluate ultra-high power density at the focus and compensate for the aberrat...
