Abstract
Free
electron lasers have finally burst upon the scientific scene offering dramatic
new possibilities in the physical, chemical and biological sciences. The FLASH
FEL facility at DESY is now open to users, and the DESY laboratory is moving
toward the XFEL hard X-ray facility. LCLS has generated the first light:

FERMI@Elettra
FEL is in construction.
SPring-8
Compact SASE Source (Japan) and MAX4 (Sweden) can all be expected to have user
programs in the next years.
These
radiation sources can produce light pulses with peak brilliance as much as ten
orders of magnitude higher than the pulses generated in present third
generation synchrotron light sources and with photon energies ranging from the
VUV to the hard X-rays, i.e. from about 10 eV (120 nm) to 10 keV (0.12 nm).
At
this light new experiments will be reviewed with attention for:
• Single Shot
Experiments (High Peak Brilliance Experiments)
• Pump-Probe
Experiments (Experiments in both the time and frequency domains)
• High Energy
Resolution Experiments (Experiments in the Frequency and Time Domain, non- linear spectroscopy experiments).
