Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
20 words
The x-ray laser defined in claim 1, wherein said means for producing a beam of radiation comprises a pulsed laser.
Claim 2
Dependent Claim
15 words
The x-ray laser defined in claim 1, wherein said lasing medium comprises a metallic filament.
Claim 3
Dependent Claim
22 words
The x-ray laser defined in claim 3, wherein said filament is selected from the group consisting of aluminum, titanium, iron, and copper.
Claim 4
Dependent Claim
19 words
The x-ray laser defined in claim 1, wherein said optical phasing network comprises a corrector plate and a lens.
Claim 5
Dependent Claim
83 words
The x-ray laser defined in claim 1, wherein said lasing medium comprises a filament configured as a hollow fiber which the heating pulse causes to radially implode to high density and temperature prior to subsequent hydrodynamic relaxation and population inversion creation, so as to be able to further concentrate the energy of the heating pulse in space and time and afford the creation of population inversions in elements of higher Z thus allowing x-ray laser action involving more energetic photons to be produced.
