An unflagging development of novel X-ray laser sources has stimulated a continuous growth in the X-ray scientific community and in new types of scientific endeavours. Unprecedented progress in X-ray lasing and improvement of all observed laser beam parameters brings ever higher requirements on laser field diagnostics. One of the most challenging issues is a rigorous spatial characterization of focused X-ray laser beams. Owing to excessive radiation intensities and (sub)micron focus sizes, radiation damage, linear response and sufficient resolution power of the sensing element are important...

Nanoplasmonics and Metamaterials have in the last 15 years inspired scientists to think about photonics beyond traditional constraints imposed by natural materials in which light propagates to conceive functionalities such as subwavelength imaging and broadband ultraslow light. While most concepts have initially been demonstrated at longer wavelengths and for microwaves, they have continuously moved to optical frequencies and beyond. Embracing nonlinearity and (quantum) gain [1], exciting phenomena such as ‘dark-light’ [2] and cavity-free [3] nano-lasing and room temperature single...
