Diamond optics

Description

- Designed for high heat load applications at XFELs

- Different use cases:

   o Diamond zone plates

   o Diamond gratings for spectral monitoring

   o Split-and-delay schemes for ultra-fast pump-probe experiments

- Diamond zone plates allowing for peak power densities in the focal spot of 4x1017 W/cm2

- Combinable with the Ir-line-doubling technique
