Demonstration of Kr(L) amplification at lambda = 7.5 AA from Kr clusters in self-trapped plasma channels

Experimental evidence demonstrating amplification on the Kr super(26+) 3s arrow right 2p transition at lambda = 7.5 AA ( similar to 1652 eV) generated from a (Kr) sub(n) cluster medium in a self-trapped plasma channel produced with 248 nm femtosecond pulses is presented. The x-ray beam produced had...

Summary:Experimental evidence demonstrating amplification on the Kr super(26+) 3s arrow right 2p transition at lambda = 7.5 AA ( similar to 1652 eV) generated from a (Kr) sub(n) cluster medium in a self-trapped plasma channel produced with 248 nm femtosecond pulses is presented. The x-ray beam produced had a spectral width of similar to 3 eV and a corresponding beam diameter of similar to 150 mu m, properties that were simultaneously determined by a two-dimensional x-ray spectral image formed with an axially placed von Hamos spectrometer and a matching Thomson image of the spatial electron density generated by the x-ray propagation.
