摘要

Advances in extremenonlinear optics make it possible to efficiently upshift tabletop femtosecond lasers into the ultraviolet (EUV) and soft X-ray regions of the spectrum, to wavelengths as short as 8 A [1, 2]. In an optimized phase-matched geometry, the resultant high-order harmonics naturally emerge as fully spatially coherent beams, with ultra broad bandwidths spanning tens to hundreds of eV, corresponding to pulse durations in the few-femtosecond range. This unique light source is ideally suited for range of nano-imaging and element-specific nano-metrologies of materials, thin film and magnetic samples.
