Single-pulse characteristics of the Xe(L) amplifier on the Xe35+ (3d -> 2p) transition array at lambda congruent to 2.86 angstrom

摘要

The triple comparison of ( 1) single-pulse spectral data, recorded with a CCD-equipped von H (a) over bar mos spectrometer both axially and transversely; (2) axially measured time-integrated spectra registered on a film and (3) single-pulse x-ray images of the morphology of the self-trapped plasma channel, recorded simultaneously with the single-pulse spectra, establishes several leading characteristics of the saturated amplification observed on the Xe35+ transition array at lambda congruent to 2.86 angstrom A. The chief findings are (alpha) absolute positive correlation of amplification with the formation of a plasma channel, ( beta) a perfect spectral match of the amplified transitions in the comparison of axially recorded single-pulse and time-integrated film data and (gamma) exact spectral correspondence of both the axially registered single-pulse and time-integrated film data with single-pulse transversely measured spectra exhibiting deep spectral hole burning at the position of the Xe35+ array.
