    Notes:
    Space–time-resolved Thomson scattering was used to characterize the electron and ion temperatures in laser produced plasmas of various atomic numbers (Z=6, 13, 32, 73, 92). A Nd:glass laser with intensity between 1013 and 5×1014 W/cm2 was used to produce plasmas of relevance to laser fusion and x-ray laser studies. A comparison of the electron temperature and density deduced from Thomson scattering, x-ray spectroscopy, and lasnex hydrocode simulations is presented.

    Notes:
    The triggering and guiding of leader discharges using a plasma channel created by a sub-joule ultrashort laser pulse have been studied in a megavolt large-scale electrode configuration (3–7 m rod-plane air gap). By focusing the laser close to the positive rod electrode it has been possible, with a 400 mJ pulse, to trigger and guide leaders over distances of 3 m, to lower the leader inception voltage by 50%, and to increase the leader velocity by a factor of 10. The dynamics of the breakdown discharges with and without the laser pulse have been analyzed by means of a streak camera and of electric field and current probes. Numerical simulations have successfully reproduced many of the experimental results obtained with and without the presence of the laser plasma channel. © 2001 American Institute of Physics.

    Notes:
    The propagation of high-power short-pulse laser beams over considerable distances in air is studied both experimentally and via numerical simulations. Filaments are formed after 5–10 m and their propagation over distances in excess of 200 m is reported for the first time. The lateral dimensions of the filaments are found to range from about 100 μm to a few millimeters in diameter. The early values of plasma electron density have been inferred to be a few times 1016 cm−3 using longitudinal spectral interferometry. For 500 fs pulses and a wavelength of 1053 nm, the energy in the filament can be quite high initially (∼8 mJ) and is found to stabilize at about 1.5–2 mJ, after about 35 m. A simple model based on the nonlinear Schrödinger equation coupled to a multiphoton ionization law appears to describe several experimental results quite well. © 1999 American Institute of Physics.

    Notes:
    The design and performance is described for a high-temperature cell appropriate for kinetic and spectroscopic studies on electron-beam or electrical-discharge excited species emitting in the vacuum ultraviolet. The experimental setup operates at temperatures up to 750 K for total gas mixture pressures of up to 5 bar. Particularly, the apparatus permits investigations on the emission spectra and their temporal behavior of ionic excimer molecules after excitation with these two most-common gas laser-excitation techniques. The comparison of the quantum efficiency for the production of the vacuum ultraviolet emissions with both excitation techniques, together with the possibility to perform optical gain measurements, will allow us to evaluate whether lasing for this new class of molecules can be achieved. The performance of the experimental device is presented by investigations on the second continua of the rare gas. © 1996 American Institute of Physics.

    Notes:
    A long pulse (up to 185 ns FWHM) KrCl laser at λ=222 nm has been achieved by combining x-ray preionization and double discharge (spiker/sustainer) with fast ferrite magnetic switch. A relatively low pumping power (0.5 to 1 MW/cm3) and 25 cm gain length allows a maximum extracted energy of 115 mJ in 135 ns FWHM, with an overall energy efficiency of 0.75%.

    Notes:
    In a 2.8 m positive rod–plane air gap, we have studied how a plasma channel produced by focusing a 200 mJ ultrashort laser beam is able to trigger and guide a leader discharge. We have observed that the plasma channel allowed the lowering of the leader inception voltage by 50% and the guiding of the leader propagation on a distance of up to 2.3 m, with a tenfold increase of its speed. This led to an effective 40% reduction of the breakdown voltage. For the conditions studied here, the laser energy per unit length required to guide a leader is between 60 and 100 mJ/m. © 2000 American Institute of Physics.

    Notes:
    This paper presents an experimental and theoretical study of stimulated Brillouin scattering (SBS) in laser produced plasma using a laser pump with a duration of 8–10 psec. The experiments were performed in a preformed plasma to minimize the flow velocity and have the same plasma conditions over a large range of laser intensities. The reflectivity was then compared to theoretical results over an intensity range of 1013–2×1015 W/cm2. A short pulse was used so that the SBS was in the temporally growing regime and saturation was not an issue.

    Notes:
    Time- and two-dimensional (2-D) space-resolved monochromatic imaging is used to study the dynamics of Ne-like populations in the electron collisionally excited germanium x-ray laser. Large-scale variations in the n=3 level population, specifically the upper level of the 2s2p63d-2s2p63p laser transition, are observed in plasmas created in uniform and nonuniform irradiation conditions, and the degree of homogeneity along the amplification axis is related to the x-ray gain. The influence of inhomogeneities on the core-excited 3d-3p x-ray lasers is discussed.

    Notes:
    Abstract An X-ray preionized spiker-sustainer XeCl-excimer laser operating at high repetition frequency (1000 Hz) and 220 W of average laser power is demonstrated. The pulse energy and the pulse duration (160 ns) are virtually independent of the repetition frequency. Comparison with aC-L-C circuit shows superior properties of spiker-sustainer excitation for high-frequency operation. Furthermore, a variation of the overshoot mode is proposed.
