Dissociative Ionization of Ethanol Using 400- and 800-nm Femtosecond Laser Pulses

Abstract

AbstractWe have investigated the behavior of dissociative ionization of ethanol molecules under irradiation of 400- and 800-nm femtosecond laser pulses. When 800-nm pulses were irradiated, parent ions and fragment ions generated at C-C bond breaking were dominant. On the other hand, when 400-nm pulses were irradiated, fragment ions generated at C-0 bond breaking showed significant increase. When irradiating both 400- and 800-nm pulses and changing the time delay between these pulses, different photofragmentation occurs depending on which pulse is irradiated first.KeywordsSecond Harmonic GenerationBond BreakingDissociative IonizationChirp RateIntense Laser FieldThese keywords were added by machine and not by the authors.
