課程說明:
The course provides the essential knowledge to understand the properties of
Ultrafast Extreme Ultraviolet
Radiation (EUV). After a comprehensive review of different EUV pulse
generation approaches, different
temporal and spatial characterization methods will be discussed in detail.
The EUV mirror coating
technique, EUV imaging and a few main Light-matter interaction phenomena
will also be introduced. Some
special application topics shall be selected for further discussion at the
end of this class.
