23 March 2012 Laser-produced plasma UTA emission in 3-7nm spectral region

We demonstrate a table-top strong band emission water window source based on laser-produced high-Z plasmas. Resonance emission from multiply charged ions merges to produce intense unresolved transition arrays in the 2 to 4 nm region, extending below the carbon K edge (4.37 nm). Arrays resulting from n = 4-n = 4 transitions are overlaid with n = 4-n = 5 emission and shift to shorter wavelength with increasing atomic number. Under spectral analysis a guideline for microscope construction design for single-shot live cell imaging is proposed based on the use of a bismuth plasma source, coupled with multilayer mirror optics.
