The study of target injection, detection, measurement of laser focal point, and laser beam steering have started under co-research in Japan. The smooth-bore gas gun is developed for accurate injection. The applications of divergent laser beam and Arago spot are described for accurate measurement of target position and laser focal point. Magnetic lens for target trajectory adjustment by centerin...

We report on the operating parameters and laser output pulse characteristics of an extremely compact discharge-pumped 46.9-nm laser of a size comparable with that of many widely utilized visible and ultraviolet gas lasers. This capillary-discharge laser generated subnanosecond laser pulses with energies of as much as 25microJ by single-pass amplification in an 18.6-cm-long argon-plasma column. ...

Flue gas regulations have been enacted into law in order to prevent air pollution in countries such as Japan, Europe and China. With a conventional-type continuous flue gas measuring system consisting of a sampling-type gas analyzer that samples flue gas and performs pre-processing, the realization of long-term stable measurements has encountered such problems as requiring the removal of blocka...

Title of Dissertation: HIGH POWER NONLINEAR PROPAGATION OF LASER PULSES IN TENUOUS GASES AND PLASMA CHANNELS Jianzhou Wu, Doctor of Philosophy, 2005 Dissertation Directed By: Professor Thomas M. Antonsen, Jr. Department of Physics The nonlinear propagation over long distances of moderate intensity laser pulses in tenuous gases is studied. The dynamics of these pulses will be affected by nonline...

The Hildebrand solubility parameters have been calculated for eight ionic liquids. Retention data from the inverse gas chromatography measurements of the activity coefficients at infinite dilution were used for the calculation. From the solubility parameters, the enthalpies of vaporization of ionic liquids were estimated. Results are compared with solubility parameters estimated by different me...

Current interest in the shipment of liquefied natural gas (LNG) has renewed the debate about the safety of shipping large volumes of flammable fuels. The size of a spreading pool following a release of LNG from an LNG tank ship has been the subject of numerous papers and studies dating back to the mid-1970s. Several papers have presented idealized views of how the LNG would be released and spre...

We describe a four-frame picosecond green laser interferometer developed at the Neptune Laboratory at UCLA. This diagnostic is applied for measuring the dynamics of CO2 laser produced plasmas in a He gas jet. An example of results of the modification of the plasma density profile by the radiation pressure of the laser pulse is presented.
