Localized behavior of laser induced metallic plasmas has been investigated using Langmuir probe as an electrostatic diagnostic tool. A Q-switched Nd:YAG pulsed laser (1064nm, 12ns, 1.1MW) is tightly focused on metal targets (Cu, Zn, Cd, Ag, Pt and Au) having dimensions 2×2×0.2cm 3 under vacuum ∼10 −3 torr. The varying biasing voltages are applied to Langmuir probe. The electric signals...
The influence of external magnetic field on the significant parameters of electrons from laser induced plasma (LIP) is investigated. A Q-switched Nd:YAG laser (1064nm, 9–14ns, 10mJ, 1.1MW) is focused on annealed, 4N pure (99.99%) Silver target (2×2×0.2cm 3 ) for production of plasma under vacuum ∼10 −3 torr. Temperature, density and energy measurements for electrons were made by self...
The most significant parameters of laser-induced plasma are investigated here experimentally. Pure platinum targets of 4N were irradiated both in air and under vacuum (∼10 −3 Torr) by Q-switched Nd: YAG laser (1064nm, 10mJ, 9–14ns, 1.1MW). A self fabricated Langmuir probe was used as an electric diagnostic tool. Varying voltages were applied to the probe and the corresponding values of currents...
