Using small amounts of optical energy, it is possible to drive matter with relativistic intensity. We show unique energy transport properties, X-ray production, and efficient attosecond phenomena coming from microscopic plasmas driven by precisely fo

We are studying shock induced melting using laser produced shock waves in tin foils. The diagnostics used for these studies include pump‐probe reflectivity and interferometry using 40fs pulses. Rear surface expansion data from the interferometer su

Using femtosecond microscopy, we observe a thermal/ionization front expand radially at ∼ 108 cm/s from a λ2-size spot of an aluminum target excited at >1018 W/cm2. Numerical modeling shows transport is predominantly radiative and may be initially

We present time-series VI photometry of the metal-rich globular cluster NGC 6316. Our color-magnitude diagrams show a predominantly red-clump horizontal branch morphology with no evidence of the blue extensions seen in NGC 6388 and NGC 6441. Our data

The dynamics of high strain rate shock waves driven by a subnanosecond laser pulse in thin tin slabs have been investigated. These shocks, with pressure up to 1 Mbar, have been diagnosed with an 800 nm wavelength ultrafast laser pulse in a pump-probe

Using femtosecond microscopy, we observe subpicosecond transport of thermal energy radially outward from a micrometer-sized spot of an aluminum target following P-polarized excitation at10(18) W/cm2 with a 24 fs pulse. The rapid expansion coincides w

A planar Al target is excited by a 25 fs laser pulse focused to intensity up to 3×1018 W/cm2 in a ∼1 μm radius spot; subsequent heat propagation along the target surface, imaged by a delayed probe pulse, appears as a roughly circular area of redu
