Limiting parameters of the x-ray lasers
- Lebedev Physics Institute, Moscow (Russian Federation)
Recent progress in free-electron lasers is do to such advantages as tunability, ability to operate at high power or to extend into X-ray regions. The scaling of fre-electron and free-ion lasers down to X-ray regime is analyzed theoretically. A production of a relativistic multilayer ion mirror and hard and high power electromagnetic radiation by reflection from this mirror are discussed. The reflectivity of the mirror is rather high because of the cross-section of the backward Rayleigh scattering of photon light by non-fully stripped relativistic ions ({approximately} {lambda}{sup 2}) is much greater ({approximately} 10 {divided_by} 15 orders) then Thompson one ({approximately}r{sub e}{sup 2}). This position is valid even in the case of non-monochromatic laser light ({Delta}{omega}/{omega}{approximately} 10{sup -4}). Ion cooling both in longitudinal plane and three-dimensional radiation ion cooling had been proposed based on this observation. The using of these cooling techniques will permit to store high current and low emittance relativistic ion beams in storage rings. The bunched ion beam can be used in ordinary Free-Ion Lasers as well. After bunching the ion beam can be extracted from the storage ring in this case.
