Study on the damage threshold of XUV and soft X-rays optical components exposed to femtosecond pulses
The optical components for the harmonics guiding and diffraction are in most cases exposed to the pump beam as well. On the other hand, they are different in structure with respect to laser optics.
Thin coating High surface accuracy
Single element: Au, Ir, Pt
