Description
Summary:High harmonics generation (HHG) of coherent extreme ultraviolet (EUV) radiation enables ultrafast pump-probe spectroscopy with attosecond-scale timing resolutions. Yet beam control of generated EUV radiation remains a major challenge for handy implementation of ultrafast spectroscopy particularly for nano-micro samples. Here, we demonstrate a solid-based HHG scheme that incorporates non-collinear illumination to perform the propagation control of EUV harmonics by wavefront phase manipulation via a spatial light modulator. Further, our solid-based non-collinear HHG scheme converts EUV harmonics to Bessel beams without extra optics for beam focusing, offering a useful tool for diverse EUV applications of metrology and fabrication.
