Abstract


Experiments were performed to find out plasma parameters for Nickel and Titanium metals which were irradiated in air (1 atm) to produce plasma plume using Q switched Nd: YAG pulsed laser of 1.1 MW, 10 m J, 1064 nm and 9-14 ns. Langmuir probe was used as a diagnostic tool. The signals at different probe voltages were recorded on digital storage oscilloscope. The information carried by the signals was utilized to calculate electron density, electron temperature, Debye’s length and number of particles in Debye’s sphere. The study shows that the calculated values of these parameters for Nickel and Titanium are different except Debye’s length. Plasma parameters strongly depend on probe potentials, material used and ambient conditions.
