Challenges toward attosecond and zeptosecond XFELs | |
|
||
| The X-ray free electron lasers (XFELs) have extended the wavelength tunability of laser sources to hard X-ray regions and have attracted many experimental users from laser science community as well as synchrotron radiation. In addition, the seeding technique which was demonstrated in LCLS in 2012 has drastically improved the temporal coherence of XFELs. Nevertheless, there still remains an important technical challenge in XFELs: How to control the pulse length, especially toward shorter values? Recently, several ideas have been proposed to resolve this issue by means of controlling the timing between X-ray and electron beams. This talk will review novel concepts toward future XFELs with attosecond and zeptosecond pulse lengths. | ||
