Complete characterization of phase and amplitude of bichromatic extreme ultraviolet light
Résumé
Intense, mutually coherent beams of multiharmonic extreme ultraviolet light can now be created using
seeded free-electron lasers, and the phase difference between harmonics can be tuned with attosecond
accuracy. However, the absolute value of the phase is generally not determined. We present a method for
determining precisely the absolute phase relationship of a fundamental wavelength and its second
harmonic, as well as the amplitude ratio. Only a few easily calculated theoretical parameters are required in
addition to the experimental data.
