| Research Abstract |
To realize a new controlling method for atoms/molecules with intense laser fields, we have made the following two findings for photo-ionization of ethanol molecules in short-pulse near infrared laser fields at 790 nm. (1) The channel specific photoelectron spectra correlated with the produced ion species, which have been obtained by measuring the electron and ion in coincidence, depend on the ellipticity of the laser polarization. (2) In additional laser fields at the longer wavelength of 1.3 mm, the ion yield ratio depends on time delay between the two laser pulses and an angle between the 790 nm and 1.3 mm polarization directions.
