The primary focus of this paper is the optical absorption spectrum, denoted as I'n, of gold (Ag) plasma, analyzed through the stimulated laser breakup spectroscopy technique. To establish the precise relationship between light beam energies and the plasma characteristics, measurements of emission line intensities and plasma properties were conducted. The electron density (ne) and temperature (Te) were calculated using the classic Boltzmann plot method and the McWhirter criteria. At the critical wavelength of 1064 nm, the data points for electron density (ne) ranged from 2.3x10^17 to 3.7x10^17 mm, while the temperature (Te) spanned from 6064K to 4507K. For Ag-ba, the electron density varied between 9.36x10^16 to 1.19x10^17 cm^-3. The overall electron temperature (Te) exhibited a sharp increase with rising light beam energy, a common trend observed across the studies, as electron density also increased proportionally with energy.
