HIGH-POWER ULTRAFAST FIBER LASERS

 

Sources of short-wavelength radiation, such as synchrotrons or free-electron lasers, have already enabled numerous applications and will facilitate more seminal studies. On the other hand, sources of coherent extreme ultraviolet to soft x-ray radiation via high-harmonic generation (HHG) of ultrashort-pulse lasers have gained significant attention in the last years due to their enormous potential to address a plethora of applications in a cost-effective and tabletop format. Therefore, they constitute a complementary source to large-scale facilities. The photon-flux values obtained by Fiber-laser-driven HHG sources can be considered the highest of all laser systems for photon energies between 20-150 eV. AFS ultrafast fiber lasers are ideal high-harmonic drivers. These turnkey HHG beamlines can address several applications in the EUV to X-ray spectral region.
