Abstract

A semiempirical model is developed for an optically thick inhomogeneous laser induced plasma (LIP). The model describes the time evolution of the plasma continuum and specific atomic emission after the laser pulse has terminated and interaction with the target material has ended. Local thermodynamic equilibrium (LTE) is assumed, allowing application of the collision-dominated plasma model and standard statistical distributions. Calculations (see Figure) are performed for a two-component Si/N system.
