Popis: |
Ultraviolet and extreme ultraviolet electric-fields produced by relativistic electrons in an undulator of a synchrotron light source are characterized by using spectral phase interferometry for direct electric-field reconstruction (SPIDER). A tandem undulator with a phase shifter produces a pair of wavelength shifted wave packets with some delay. The interferogram between the pair of the wave packets is analyzed with a SPIDER algorithm, which is widely used for ultrashort pulse characterization. As a result, a 10-cycle square shaped electric-field is reconstructed. The waveform corresponds to the radiation from an electron accelerated with the undulator which consists of 10 periods of permanent magnets. |
