Reflection of attosecond x-ray free electron laser pulses
Review of Scientific Instruments
In order to utilize hard x-ray free electron lasers (XFEL's) when they are extended to attosecond pulse lengths, it is necessary to choose optical elements with minimal response time. Specular grazing incidence optics made of low-Z materials are popular candidates for reflectors since they are likely to withstand x-ray damage and provide sufficiently large reflectivities. Using linear-optics reflection theory, we calculated the transient reflectivity of a delta-function electric pulse from adoi:10.1063/1.2428271 pmid:17503904 fatcat:iqg3y5nybrfihmfwi7gwrpeo5y
