Standing-wave saturation resonances in the CO2 10.6-μ transitions observed in a low-pressure room-temperature absorber gas

Abstract

The standing-wave saturation resonances are observed by subjecting the CO2 absorber gas to the standing-wave 10.6-μ laser field and detecting the change induced in the entire 4.3-μ (001) → (000) spontaneous emission band as the laser frequency is tuned within the Doppler profile of a specific 10.6-μ transition. Long-term stabilization on any oscillating transition is achieved. © 1970 The American Institute of Physics.
