Abstract
Investigating complex systems and accessing information has been of interest to researchers for years. The desired system in this research includes the investigation of the plasma resulting from the interaction of the laser with the desired substance of the research. Air is the material of choice for producing plasma in interac-tion with the laser. We used Nd:YAG laser for incident beam to interact with air matter. By the interaction of laser with air, plasma was formed. In the following, it is possible to check the plasma density by scanning the plasma resulting from the interaction of the laser with air. Therefore, in order to determine the electron density by the Saha method, we first need to calculate the electron temperature, which was calculated using the spectral line pair intensity ratio method of the plasma temperature equal to Kelvin. In the continuation of the research, the electron density was measured using Saha's equation
