Abstract
⺠Investigations on ions emitted from Laser Induced Plasma ⺠A Q-switched Ndw: YAG pulsed laser at 1064 nm, 9-14 ns and 1.1 MW, is focused on 4 N pure Gold (Au) and Platinum (Pt) targets at 45° with the normal to the target ⺠The emitted ions thus are detected by CR-39 Solid State Nuclear Track Detectors (SSNTD's), placed at angles 0°, 30°, 60°, and 90° with respect to the target normal. ⺠The distance between the targets and detectors is 9 cm ⺠The experiments are performed under a vacuum â¼10â3 torr and the ion tracks are recorded on SSNTD's for 300 laser shots. ⺠The etched detectors are analyzed with the help of Motic Images Optical Microscope (Motic Advance 3.1). ⺠The flux of ions exhibits anisotropic behavior where as maximum energies of these ions are not only anisotropic but also forward peaked. ⺠YAG Laser, Ions Emission, SSNTD's, Anisotropy and Forward Peaking and Vacuum
