Abstract

Intense high-order harmonic radiation induces nonlinear optical phenomena, such as two or three photon absorption process in the vacuum and extreme ultraviolet wavelength region. Fragment ion yields via two-photon absorption process of N2 and CO2 molecules were utilized as correlated signals of the attosecond pulse train in the measurement of the interferometric autocorrelation (IAC) [1,2], while the interference fringes on the IAC traces can be utilized for identifying the ionization/dissociation pathways of ion fragments. We call this method nonlinear Fourier-transform spectroscopy (NFTS). We have demonstrated the NFTS of D2, resulting in the decomposition of the measured velocity map image into three images in accordance with each pathway [3]. Nevertheless, we could not observe the whole feature of the ionization because the scanning range of the IAC measurement was limited to a few cycle periods of the fundamental laser field. In this paper, we present results of NFTS of D2 by extending the delay range of IAC without losing sampling resolution of scanning by virtue of high-repetition rate (100 Hz) and short pulse duration (sub 15fs) of the driving fundamental laser pulse[4]. We compare the spectral shape obtained from the NFTS to that measured directly with a spectrometer because the delay range is much broader than the pulse duration of the fundamental pulse.
