✦ Synopsis

Single shot nanosecond polarization resolved laser induced breakdown spectroscopy is introduced to spectrally analyse solid sample, e.g. copper. It is shown that continuum background emission of plasma generated by such laser pulse is much strongly polarized than discrete line radiation. By using the PRLIBS technique, continuum background emission is effectively suppressed. Furthermore, it is illustrated that polarization state of continuum emission in copper sample is mostly in vertical direction and, also, does not depend on laser beam polarization.

The line-broadening mechanism for three emission lines (510.55, 515.32, and 521.82 nm) in laser-induced copper plasma was investigated by time-resolved laser-induced breakdown spectroscopy. Two emission lines observed at 515.32 and 521.82 nm revealed a dramatic decrease in linewidth as the delay of
