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.
