[Report] Time-resolved x-ray absorption spectroscopy with a water window high-harmonic source 1Science: Current Issue / by Yoann Pertot / 1 Time-resolved x-ray absorption spectroscopy (TR-XAS) has so far practically been limited to large-scale facilities, to subpicosecond temporal resolution, and to the condensed phase.
This picture shows an actual image of a coherent (laser-like) X-ray beam. In contrast to the incoherent (light-bulb-like) light emitted in all directions from a Roentgen X-ray tube, the X-rays produced by high harmonic generation emerge as well-directed, laser-like, beams.

In the high-harmonic generation process several harmonics of the fundamental radiation are generated (Fig. 7) such that a dispersive element is necessary to separate a particular harmonic frequency. Therefore a spherical diffraction grating (700 lines/mm) is illuminated at a deviation angle of 161.8 exploiting the total external reflection (Fig. 6).

Conclusion: We have demonstrated the generation of tunable pulses between 520 and 1000 nm (250 to 1000 nm adding a second harmonic generator) with pulse durations in the range 14 to 30 fs and energies from 25 to 750 nJ at a high repetition rate of 2 MHz. With minor adjustments, our NOPA can also be operated in a broadband configuration able to generate 6.0 fs pulses at 850 nm as well as a spectrum.
