Pulsed laser ablation techniques for the production of atomic beam~Chae & Park, 1997; Breton et al, 1980;Kadar-Kallen & Bonin, 1994! Whenever a high power laser is focused on a target material, the laser fluence or the intensity at the focal spot is very large, and therefore substantial portion of the material ejected out from the target is converted into the plasma, and the expansion of the material is hemispherical Alti & Khare, 2006a;Anan'in et al, 1991;Weaver & Lewis, 1996;Mishra & Thareja, 1999!. It has ability to produce high atomic flux with energies from cold to super-thermal range.…”
