Abstract EN
Aluminum plasma was generated by the irradiation of the target with Nd: YAG laser operated at a wavelength of 1064 nm.
The effect of laser power density and the working pressure on spectral lines generating by laser ablation, were detected by using optical spectroscopy.
The electron density was measured using the Stark broadening of aluminum lines and the electron temperature by Boltzmann plot method it is one of the methods that are used.
The electron temperature Te, electron density ne, plasma frequency and Debye length increased with increasing the laser peak power.
The electron temperature decrease with increasing gas pressure.
