Absorption and Stimulated Emission by a Thin Slab Obeying the Lorentz Oscillator Model

In his celebrated 1916-17 papers in which he proposed the A and B coefficients for the spontaneous and stimulated emission of energy quanta from excited atoms, Einstein conjectured that stimulated emission involves the release of individual quanta (later dubbed "photons") along the direction of an incident photon with the same...
