Parameters in a dynamically compressed xenon plasma laser

Laser action from triply ionized xenon has been found to occur during the dynamical contraction of the xenon plasma column. Laser lines between the near ultraviolet and the orange portion of the spectrum have been detected. Their peak powers, time of occurrence, duration, wavelength, and coherence length have been measured. Optimum currents and pressures have been found and compared with other published results. In addition, a simplified model of a pinching plasma has been used, in conjunction with streak camera pictures of the contracting column and time-resolved interferometric measurements of the electron density to estimate electron temperatures. Values of the electron density, temperature, and conductivity of the xenon plasma compare well with published results applicable to high-current pulsed-argon ion lasers.
