Complete characterization of single attosecond pulses by the modified spectral phase interferometry is presented considering the frequency-dependent spectral shear. The results show no principle limitation of characte...
We greatly improved our angularly-dispersed NOPA system and introduced a new stretcher for seed pulses. Consequently, we achieved the broadest gain bandwidth ranging from 500 to 1030 nm with output pulse energy of 45 ...

We present the complete characterization of single attosecond pulses by the modified SPIDER method with a frequency-dependent spectral shear. The validity of this method shows no principle limitation of characterizing...
We combined a pump-probe technique with optical sum frequency microscopy, and demonstrated a time-resolved SF intensity image observation of an H-Si(111) surface in ultrahigh vacuum (UHV) conditions. After pump-light ...

The frequency of the Rabi oscillation driven by a periodic external field varies with the parameters of the external field, e.g., frequency and amplitude, and it becomes zero at some points of the parameters, which is called coherent destruction of tunneling. This phenomenon is understood as a degeneracy of the Floquet quasienergies as a function of the parameters. We prove that the time-reversal symmetry of the external field is a necessary condition of the degeneracy. We demonstrate the gap opening in the quasienergy spectrum in asymmetrically periodically driven systems. Moreover, an adiabatic transition of the Floquet states is demonstrated and analyzed in the analogy to the Landau-Zener transition.
