    Demonstration of Pulse Switching with > 1011 Prepulse Contrast by Cascaded Optical Parametric Amplification

    The use of chirped-pulse amplification (CPA) in high-energy systems allows the generation of high-peak power and ultrahigh intensity, and has led to intensities greater than 1020 W · cm−2 [1]–[3]. These systems a...

    Short-pulse, high-brightness X-ray production with the PLEIADES Thomson-scattering source

    PLEIADES is a compact, tunable, high-brightness, ultra-short-pulse, Thomson-scattering X-ray source. Picosecond pulses of hard X-rays (10–200 keV) are created by colliding an ultra-relativistic (20–100 MeV), p...

    Direct Observation of Ultrafast Non-thermal Melting by Ultrafast X-ray Diffraction

    Ultrafast nonthermal melting of femtosecond laser-irradiated germanium was observed directly for the first time using sub-picosecond. 1.54-angstrom x-ray diffraction. Such measurements allow the study of trans...

    Chirped-Pulse Amplifiaction with a Fiber Stretcher and a Grism Compressor

    We demonstrate chirped-pulse amplification of femtosecond pulses using a fiber stretcher. We use a grism pair to achieve the highest single-stage compression factor (750) ever obtained from a fiber.
