Abstract
This research paper mainly aims to investigate the effect of polarization and susceptibility in amplifying light and producing laser using Maxwell equations, which consist of polarization term, and using quantited density matrix. It was shown that the polarization and the susceptibility both contributors to amplification. Strictly speaking, both stimulated photons and spontaneous photons, which in the direction of the field increase polarization.
