Plume splitting and sharpening in laser-produced aluminium plasma
Plume splitting and sharpening were observed in laser-produced aluminium plasma created using 532 nm, 8 ns pulses from a frequency doubled Nd : YAG laser. Measurements were made using 2 ns gated fast photography as well as space and time resolved optical emission spectroscopy. The motion of the leading edge of the plume was studied with several background air pressures and the expansion of the ...

Introduction: There are many reports published about the use of cold atmospheric plasma in cancer treatment recently. In this way, the selective effects of cold plasma on the breast (MDA-MB-231) and cervical (Hela) cancer cells were studied as a new cancer treatment method. Materials and Methods: In this study, cold atmospheric pressure plasma was generated using a plasma jet reactor and also o...
متن کاملEmission features of femtosecond laser ablated carbon plasma in ambient helium
We investigated the optical emission features of plasmas produced by 800 nm, 40 fs ultrafast laser pulses on a carbon target in the presence of ambient helium or nitrogen gases at varied pressures. Fast photography employing intensified charge coupled device, optical emission spectroscopy, and temporally spatially resolved optical time of flight emission spectroscopy were used as diagnostic too...

A quantitative analysis of trace lead in tin-base lead-free solder was carried out with laser-induced plasma spectroscopy (LIPS). In order to evaluate the applicability of the technique for rapid in situ analytical purposes, measurements were performed in air at atmospheric pressure, and the emission characteristics of the plasma produced by a Q-switched Nd:YAG laser over a laser energy range o...
متن کاملGas dynamic effects on formation of carbon dimers in laser-produced plasmas
We investigated the effect of helium and nitrogen pressures on the dynamics of molecular species formation during laser ablation of carbon. For producing plasmas, planar carbon targets were irradiated with 1064 nm, 6 ns pulses from an Nd:yttrium aluminum garnet laser. The emission from excited C2 and CN molecules was studied using space resolved optical time-of-flight emission spectroscopy and ...
