Effect of ambient environment and magnetic field on laser-induced cobalt plasma

Plasma parameters of magnetically confined Cobalt (Co) plasma have been evaluated by using laser-induced breakdown spectroscopy at various laser irradiances, under different ambient pressures two environments such as Ar and Ne time delays. The effect irradiance on Co is exposed in the presence absence a Transverse Magnetic field (TMF) while keeping environmental gas pressure constant, i.e., 10 Torr. For this purpose, pellets were to Nd: YAG (1064 nm, ns) irradiances ranging from 1 2.9 GW cm−2. To investigate impact background pressures, varying 5 760 Torr Ne. In case delay variation, Texc ne decrease exponentially. A significantly pronounced an external TMF strength 0.9 T time-integrated has revealed. are considerably increased both because being constrained very small region due which collisions will be enhanced. Implementation responsible for confinement plasma. surface morphology laser-irradiated samples was also discussed confirm TMF. Fine uniform structures observed treated SEM technique.
