High harmonics generation: Spatial characterisation and applications

Research output: Contribution to conferencePaperpeer-review

Abstract

We present a full optimization of the high harmonics wave-front thanks to the use of a soft x-ray Hartmann sensor. The sensor was calibrated using high harmonics source with a λ/50 accuracy. We observed relatively good high harmonics wave-front, two times the diffraction-limit, with astigmatism as the dominant aberration for any interaction parameters.The influence of high harmonic generation parameters was also studied in particularly the influence of the infra-red wave-front. This wave front quality allows applications by focalization of this beam. We present experiment we performed on damage target and holography.
