Outline of Final Research Achievements

We study the efficient EUV & soft x-ray sources for lithography and bio-imaging applications based on laser-produced high-Z ions. In order to produce the high-power emission, the mid-IR laser pulse for high-Z plasmas is one of key technology. Recent progress has been showed the laser development and discuss the experimental data to achieve the lab-scale table-top, efficiency, high-brightness high-Z plasma EUV-soft x-ray sources for in vivo bio-imaging applications.
