✦ Synopsis

Spatially resolved emission spectra of laser-produced plasmas from metal samples are reported . A pulsed XeCI excimer laser delivering fluences in the range 2.3-4.7 J cm-2 at 308 nm was used. Line emissionn was detected using a charge-coupled device. The effect of laser parameters on the plasma morphology was investigated for silver, copper and mercury targets. The emission spectrum of a 18-carats gold sample is discussed .
