Abstract

The results of the investigations of a selective laser-induced breakdown (SLIB) of xenon in the 440-600-nm spectral region are presented. The SLIB was initiated by 10-ns dye laser pulses with the spectral bandwidth of 0.01 nm (FWHM). The beam was focused into an optical cell with xenon, which gave a power density of up to 10¹¹ W/cm² in a 10 μm beam waist. The time-integrated emission of the laser-produced plasma as a function of wavelength, gas pressure, laser energy, and excitation geometry was measured in a direction perpendicular to the laser beam.
