    Notes:
    The conversion efficiency into kilovolt line radiation for 248-nm light at 1017 W/cm2 on an aluminum target is measured. The x-ray yield is found to increase with the scale length of the target plasma. The interaction is modeled as resonance absorption, and the plasma scale length is determined from the prelase energy and irradiance.

    Notes:
    Ultrafast time-resolved absorption spectroscopy in the hard ultraviolet has been used to investigate the photodissociation of gas-phase CF2Br2 photolyzed at 248 nm. The broadband spectra obtained in the 250–265 nm region have shown that absorption of a single photon activates a two-step sequential elimination of the molecule's two bromine atoms, leaving the product CF2 radical in the ground or first-excited vibrational state of its ν2 bending mode. The spectra also demonstrate the direct detection of the vibrationally hot CF2Br intermediate species itself. We interpret the ∼6 ps time scale over which the diffuse CF2Br spectrum evolves as evidence for slow intramolecular vibrational redistribution within this molecule.

    Notes:
    An x-ray streak camera is used to diagnose a laser-produced Al plasma with time resolution of ∼10 ps. A streak record of filtered emission and a time-integrated transmission grating spectrum reveal that the plasma radiation is dominated by emission from He- and H-like resonance lines.

    The steady-state and dynamic gain characteristics in a KrF amplifier are studied with the use of 1 ps pulses. A saturation energy density in the range 1.8–2.0±0.2 mJ/cm2 is measured. The recovery of the small-signal gain coefficient exhibits two recovery processes with time constants of 67±10 ps and 2.0±0.2 ns.

    Notes:
    We describe the generation of terahertz radiation by optical rectification in an electro-optic crystal mosaic. The mosaic is constructed from four single crystals of the organic salt dimethyl amino 4-N-methylstilbazolium tosylate and is approximately 1 cm2 in area. We characterize both the optical rectification efficiency and the spatial and temporal profiles of the generated terahertz beam, and find that the mosaic performs as well as a single crystal. © 1995 American Institute of Physics.

    Notes:
    We report on the scalability of generating terahertz radiation by optical rectification with the electro-optic materials LiNbO3, LiTaO3, and dimethyl amino 4-N-methylstilbazolium tosylate (DAST). A Ti:sapphire laser system, producing 215 fs, 20 mJ pulses at 810 nm, was used for the experiment. Using LiNbO3 and LiTaO3, the peak of the generated terahertz electric field was found to scale linearly with increasing optical fluence for fluences up to 60 mJ/cm2, while with DAST the peak field scaled sublinearly in this fluence range. © 1995 American Institute of Physics.

    Notes:
    We have studied the interaction of 290-fs, 308-nm laser pulses with aluminum targets at irradiances exceeding 5×1018 W/cm2. The x-ray spectrum is dominated by the H- and He-like lines from aluminum, with the brightest lines radiating 0.8% of the incident laser light energy. This fraction is close to that measured at 50 times less irradiance, but occurs at a slightly higher ionization stage. The x rays are emitted from a region of subcritical electron density at 3–6×1021 W cm−3. The radiance of the 1.73-keV Lα line is measured to be 4×1012 W/cm2/sr.

    Notes:
    We demonstrate ultrafast dynamical imaging of surfaces using a junction-mixing scanning tunneling microscope. We detect picosecond transient voltage pulses on a microstrip transmission line and demonstrate a temporal resolution (full width at half maximum) of 8 ps. We show that the time resolution achieved in these experiments is limited mostly by the microstrip geometry and can be significantly improved by reducing the value of the transmission line impedance. By dynamically imaging the microstrip line and detecting picosecond voltage pulses propagating on a patterned metal-on-metal (Ti/Pt) structure, we demonstrate that 1 nm spatial resolution is achievable for a 13 ps (full width at half maximum) transient correlated signal. © 2002 American Institute of Physics.

    Notes:
    Air sampling was done in a UK bakery and a flour mill with an eight-stage cascade impactor to determine the size of airborne flour particles. The concentration of captured material was determined by a competitive inhibition radioimmunoassay. Comparison of the different sites revealed that 8.79% and 52.14% of the particles in the bakery dough-brake and roll-production areas had a diameter 〈inlineGraphic alt="leqslant R: less-than-or-eq, slant" extraInfo="nonStandardEntity" href="urn:x-wiley:01054538:ALL891:les" location="les.gif"/〉6.0 μm, respectively, and 19.7% of the particles in the flour mill packing area were of this size. We conclude that in dusty areas up to 20% of the airborne flour particles are of a diameter likely to allow them to be deposited in the bronchial airways and alveoli.

    We have measured the conversion efficiency, as well as the spectral and temporal x-ray output of H- and He-like carbon line emission, from a thin foil of polypropylene that has been irradiated with subpicosecond KrF laser pulses. The effect of amplified spontaneous emission prepulse on the x-ray conversion process, as well as the application of these x-ray "flashlamps'' toward pumping soft x-ray lasers, is discussed.

    Notes:
    A laser shadowgraphy system for high-speed imaging of a convergent cylindrical shockwave generated by an electromagnetically driven solid density liner implosion in Lucite is described. The laser shadowgraphy system utilizes an advanced high-energy, long-pulse, frequency-doubled Nd:YAG laser for target illumination and a fast framing camera for multiple frame imaging of the shockwave as it radially converges and transits the Lucite. The time window resolution is 10 ns as determined by the fastest exposure time capable with the camera. Two on-axis symmetric implosions and two off-axis asymmetric implosion experiments were fielded at the Air Force Research Laboratory's Shiva Star 4.2 MJ capacitor bank z-pinch facility. For each experimental shot, the shadowgraphy system captured several frames of shadowgraph images as the shockwave moved through the Lucite. Analysis of the shockwave shadowgraph image shapes is done by fitting each shadowgraph image to a generic elliptical fit function and plotting the resultant two-dimensional image fits for comparison. For the on-axis symmetric implosion shots, a radial trajectory plot is extracted and a radial shock velocity is calculated. The Lucite shock speed is seen to increase monotonically from an initial velocity of 7.9 mm/μs to a near final velocity of 13.4 mm/μs as convergence effects dominate the shock speed calculated at small radii. © 2001 American Institute of Physics.
