WebA reflective superachromatic phase retarder for extreme ultraviolet attosecond pulses was developed using SiC mirrors. The phase retardation at 28.0 eV is 90° with a deviation less than ±λ/50 for a bandwidth of 3.1 eV. WebResidual stress birefringence of highly reflective mirrors is a challenging problem due to its dubious origin and intricate nature. In this paper, the birefringences of highly reflective mirrors manufactured under the same deposition parameters but structured with different numbers of high- and low-refractive-index (HL) layer pairs are measured with the cavity …
