In this work, A spectroscopic research on laser-produced tin plasma using optical emission spectroscopy (OES) technology is provided. Laser-induced Sn plasma produced at various laser energy has also been defined by visible emission spectroscopy. Plasma is created by a solid tin object radiated by a pulsed laser in a room environment. A Nd:YAG laser pulse 9 ns in duration with wavelength of 1064 nm and a focal length of 10 cm in the range of energy 500-800 mJ is used to generate plasma from a planar Sn sample. The electron temperature (Te) was calculated in ratio line intensities method, while the electron density (ne) was calculated using Saha-Boltzmann equation, also another plasma parameters was calculated such as plasma (fp), Debye length (λD) and Debye number (ND). The increase in electron temperature and density was observed as a function of laser energies. Measurement of the production of the electron temperature in the rang 0.926-0.952 eV, While the electron density is in the rang (1.9×1015-2.5×1015) cm-3.
