Abstract:

The interaction of a directed beam of radiation with an absorber is described using a two level model transmitted light intensities and level populations are treated as functions of temporal and spatial independent variables and the general rate equations are given as partial differential equations. Additionally, combinations of material constants are identified as scale parameters and used to express the rate equations in nondimensional form as a hyperbolic partial differential equation in cononical form. One integration yields a time-independent relationship between two transmitted beam intensities at different wavelengths. Also described are several calibration experiments to evaluate material parameters. Author
