Abstract

We report on the lasing action for the combustion intermediate of CN in an ethanol/air flame by femtosecond laser excitation. It is confirmed that the lasing action results from amplified spontaneous emission with the population inversion achieved in the femtosecond-laser-induced plasma filament.
