Recent advancements in the “water-window” microscopy with laser-plasma SXR source based on a double stream gas-puff target

Abstract

An overview of our recent developments, regarding "water−window" soft X−ray (SXR)

A study on soft x-ray spectra from pulsed 1 μm Nd:YAG laser-induced ytterbium plasmas

“…Compared with other methods, such as electron microscopy, this soft x-ray radiation source imaging does not need special sample processing, enabling the possibility for transient imaging of intact living biological cells or original samples of frozen cells. Nowadays, characterizing and optimizing imaging light sources in the water window region are a hot research topic and in progress [12][13][14][15][16]. Highbrightness x-ray light sources based on synchrotron radiation and free electron lasers are capable of producing high resolution microscopy images, which is difficult for biological researchers in a laboratory environment to access because both facilities are very large and expensive.…”
