title = "Circularly polarized high order harmonics in the EUV photon energy range: Toward table-top nanometric magnetic imaging",
abstract = "Circularly polarized high order harmonics in the extreme ultraviolet range (18 - 27 nm) have been obtained by a two steps process. Harmonics were generated from a linearly polarized infrared laser (40 fs, 0.25 TW) focused into a neon filled gas cell. The harmonics have then been circularly polarized by a four-reflector phaseshifter. The polarization of the harmonics have been measured using a rotating multilayer broadband mirror set at an incidence angle of 45?. Fully circularly polarized radiation has been obtained with an efficiency of a few percents. This is significantly more efficient than currently demonstrated direct generation of elliptically polarized harmonics. This demonstration opens up new experimental capabilities based on high order harmonics, for example, in materials science for time-resolved nanometric magnetic imaging.",
