Paper Abstract

Plasma-based seeded soft x-ray lasers have the potential to generate high-energy, highly coherent, short pulse beam. Due to their high density, plasmas created by interaction of intense laser with solid target should store the highest amount of energy density among all plasma amplifiers. However, to-date output energy from seeded solid amplifiers remains as low as 60 nJ. We demonstrated that careful tailoring of the plasma shape is crucial for extracting energy stored in the plasma. With 1 mm wide plasma, energy as high as 22 μJ in sub-ps pulse is achievable. With such tailored plasma, gain and pumping efficiency has been increased by nearly a factor of 10 as compared to the narrower plasma amplifiers studied previously and here.
