By tuning a high pressure CO2 laser (HPL) around strong ammonia lines nearly coincident with CO2 lines an of-fresonant absorption is observed which can be confirmed by the superfluorescent MIR emission. This effect is related to a two frequency v1, v3 HPL emission in the regime of moderate pulling. Around a strong absorption line a mixed v4=2v1-v3 frequency is produced that is strongly absorbed © 1993 Plenum Publishing Corporation.
