Research with high-power short-wavelength lasers
Abstract
Three high-temperature, high-density experiments were conducted using the 10-TW, short-wavelength Novette laser system. Successful solutions to problems that arose during previous experiments with long wavelength lasers in which inertial confinement fusion (ICF), X-ray laser, and other high-temperature physics concepts were tested are demonstrated. The demonstrations are: (1) large-scale plasmas were produced in which potentially deleterious laser-plasma instabilities were collisionally damped; (2) deuterium-tritium fuel was imploded to a density of 20 g/sub cm and a pressure of 10(1) atm; (3) a 700-fold amplification of soft X rays by stimulated emission at 206 and 209 A from Se(+24) ions is observed in a laser-generated plasma. Isoelectronic scaling to 155 A in Y(+29) is also demonstrated.
