Early nitrogen emission and charge-state separation in nanosecond laser-produced tin plasma under varying pressures

The spatiotemporal evolution of nanosecond laser-produced Sn plasma was investigated under N 2 pressures from 10 −3 to 10 4 Pa using ICCD imaging and time- and space-resolved optical emission spectroscopy. The plasma evolution exhibits an early “fast” process (<100 ns) and a later “slow” process (>100 ns)(10-...
