The unique combination of the LCLS x-ray laser with high-power nanosecond and femtosecond laser beams at the Matter of Extreme Conditions allows precision pump-probe studies of high energy density plasmas. For this purpose, we are building a new 200 TW laser system to measure and uncover the underlying physics mechanism that determine the interaction of ultra intense laser beams with matter. The repetition...
We present time-resolved X-ray absorption measurements of vanadium dioxide using ionizations radiation generated by a femtosecond pulsed laser source in combination with superconducting microcalorimeters capable of measuring energies of individual radiation quanta.
Compact λ = 13.9 nm and λ = 18.9 nm lasers with record >0.1 mW average power were demonstrated using a 100 Hz repetition rate diode-pumped CPA laser. Successful scaling to λ = 10.9 nm is reported.
Experiments measuring the velocity of hohlraum-driven implosions on the National Ignition Facility (NIF) are described, including a demonstration of the required fusion-fuel velocity Vfuel > 350 km/s with a 520 TW, 1.86 MJ laser pulse.
The wavefront of a λ=18.9 nm soft x-ray beam from an injection-seeded plasma amplifier was measured using a Hartmann sensor. An optical quality superior to that of the seed, up to λ/7 rms, was obtained.
The essence of ELI-ALPS, the laser driven secondary sources ranging from X-ray and X-UV to THz with duration as short as tens of attoseconds, are designed to be available for users from 2016.
