Theoretical Study of Laser Produced Platinum Plasma

Abstract

A theoretical study of the laser produced platinum (Pt) plasma was carried out using hydrodynamic simulation program MED103. A CO₂ laser with wavelength of 10.6 µm was focused on platinum Z=78, to evaluate the spatial temporal development of hydrodynamic properties of plasma. The dectron tempertur, electron density and average charge were simulated with changing laser intensity and laser pulse width. The laser pulse duration of 20 ns was more snitable to produce emission in water window spectral region it generate higher electron temperature with lower laser intensity.
