Abstract: | This paper calculates quantum-mechanically the photoelectron energy
spectra excited by attosecond x-rays in the presence of a few-cycle
laser. A photoelectron laser phase determination method is used for
precise measurements of the pulse natural properties of x-ray
intensity and the instantaneous frequency profiles. As a direct
procedure without any previous pulse profile assumptions and
time-resolved measurements as well as data fitting analysis, this
method can be used to improve the time resolutions of attosecond
timing and measurements with metrological precision. The measurement
range is half of a laser optical cycle. |
