Abstract
The line shapes of saturation spectroscopy in optically thick two-leve l media are calculated for atomic and molecular transitions. Line narr owing and distortion effects due to propagation are presented. For Dop pler-broadened media it is shown that, due to multiphoton processes, t he natural linewidth limits the ultimate narrowing that can be reached . Thus, up to alpha(0)L = 20, only when the rate-equation approximatio n is valid subhomogeneous linewidths are expected. [S1050-2947(98)0770 8-7]
