LASER-PRODUCED PLASMA FROM SOLID CUCL.

Abstract

Summary form only given. Energy transfer processes in excimer laser ablation of inorganic solids were studied by optical emission spectroscopy of the ablated material during the first few microseconds following the laser pulse. Cuprous chloride was chosen for this study because it was the only material that had detectable molecular emission. Optical emission spectra from the plasma produced by irradiation of polycrystalline CuCl under vacuum by pulsed excimer laser radiation at 248 and 308 nm show well-resolved molecular emission bands as well J/cm**2 weak atomic Cu lines for fluences phi APP 1STH 0. 4 J/cm**2 . A typical emission spectrum of the CuCl plasma created by irradiation with 0. 22 J/cm**2 at 248 nm is shown.
