摘要：
The line shapes of saturation spectroscopy in optically thick two-level media are calculated for atomic and molecular transitions. Line narrowing and distortion effects due to propagation are presented. For Doppler-broadened media it is shown that, due to multiphoton processes, the natural linewidth limits the ultimate narrowing that can be reached. Thus, up to alpha(0)L = 20, only when the rate-equation approximation is valid subhomogeneous linewidths are expected. [S1050-2947(98)07708-7]
