WebbThe Three requisites of a Laser system are (1) Energy Source or Excitation Source for Pumping action (2) Medium Supporting population inversion called Active Medium (3) The Laser Cavity Appropriate amount of energy is to be supplied for the atoms in order excite them to higher energy levels. WebbA laser model based on feedback produced by scattering has been developed to explain the narrow linewidth emission and input-output behavior observed in scattering gain media. The model is based on the transient two-level laser equations and includes the detailed spectral properties of the dye gain system.
