TL;DR: In this article, a 2 psec temporal resolution of plasmas produced by the interaction between solid targets and a high contrast sub-picosecond table top terawatt (T3) laser at 1016 W/cm2 is used to study the basic processes which control the x-ray pulse duration.

TL;DR: From measurements of significant polarization of the He-like emission in a laser-produced plasma, a negative second-order (i.e., oblate) anisotropy of the electron velocity distribution function in the energy deposition region is inferred.

TL;DR: It is shown that x-ray-line polarization spectroscopy can be a powerful diagnostic to study laser-produced plasmas and indicate non-Maxwellian behavior and strong anisotropy due to nonlocal electron heat flow.

TL;DR: Second-harmonic conversion efficiencies of 80% for type I KDP crystals and 70% fortype II have been demonstrated with 500-fs, 1.053-μm laser pulses at intensities as high as 400 GW/cm2, indicating that self-phase modulation and cross- phase modulation may be significant.

TL;DR: Using the nonlinear propagation properties of ultrashort laser pulses in air, this article was able to produce long ionized filaments that served to guide spark discharges, where the electric field was fairly uniform and had an average value of 0.6 MV/m.
