9.To indicate the range of molecular energies that can be probed, we note that when the frequencies of the two traveling waves differ by, e.g., more than 3 times the full Doppler 1/e width the nonlinear resonance arises from molecules having —these molecules have mean kinetic energy > 10kt. In these extreme regions, however, the absorption coefficient diminishes appreciably. The resulting reduction in signal size can be recovered, at least partially, by operating at an elevated gas pressure and with a longer absorption cell; at elevated gas pressures, in turn, a larger laser power is required to cause detectable saturation.
