Abstract: 
A time resolved imaging study of pulsed laser ablated Fe and Al plasma plumes with specific
interest in the splitting of plumes into the slow and fast moving components as they expand through
the background argon gas at different pressures is reported. The material ablation was achieved
using a Q-switched Nd:YAG yttrium aluminum garnet laser operating at 532 nm with a pulse
duration of 8 ns full width at half maximum and a fluence of 30 Jcm−2 at the target surface.
Typical time resolved images with low magnification show that the splitting occurs at moderate
background gas pressures 0.5 and 1.0 mbar for Fe, and 0.2 mbar for Al plasma plumes . The plume
splitting did not occur for higher background gas pressures.
