Doppler-Free Spectroscopy of Weak Transitions: An Analytical Model Applied to Formaldehyde
arXiv:0708.0784 · doi:10.1007/s00340-007-2876-3
Abstract
Experimental observation of Doppler-free signals for weak transitions can be greatly facilitated by an estimate for their expected amplitudes. We derive an analytical model which allows the Doppler-free amplitude to be estimated for small Doppler-free signals. Application of this model to formaldehyde allows the amplitude of experimentally observed Doppler-free signals to be reproduced to within the experimental error.
