This paper represents the results of a study of angular distribution
of laser produced ions (LPI) of Al, Cu, and Ag. The angular distribution
is studied by CR-39 (SSNTD) and ion assisted sputtering experiments. A
Q-Switched Nd:YAG laser (1.064 μm, 1.1 MW) with 10 mJ pulsed energy
was used to produce the Ag ions, which were detected by CR-39 detector
mounted at −17.5°, 0°, 17.5°, 30°, 60°, and
90° from the normal to the target placed at a distance of 9 cm from
the target. Etched CR-39 detectors then observed under the Motic DMB
Series optical microscope. A bunch of ions was detected along the normal
of target due to self generated collimation of ions. This is termed as
Forward Peaking of Laser Produced Ions. Similar results were also observed
from sputtering of polished Al substrate by laser produced ions of Cu and
Sputtering of polished Cu substrate by laser produced ions of Al. The
surface morphology of the ion irradiated samples were observed under the
Scanning Electron microscope (SEM) S 300 Hi-tech. Formation of a circular
damage on the surface of the substrates by irradiation conforms the ions
collimation along the normal or Forward Peaking of ions.
