Abstract

Several coherent soft x-ray lasers are available for applications nowadays. Among them, plasma-based soft x-ray lasers promise to generate high-energy, highly coherent, short pulse beam. Solid target based amplifiers, due to the fact that his density is higher, should store a higher amount of energy. However, to-date output energy from seeded solid amplifiers remains as low as 60 nJ. We demonstrated that the extraction of the energy stored in the plasma is enhanced by carefully tailoring the plasma shape, to inhibit deleterious hydrodynamical effects. With 1 mm wide plasma, energy as high as 22 μJ in sub-ps pulse is achievable. Not only the energy extracted is higher in these tailored plasmas but also gain and pumping efficiency are increased by nearly a factor of ten as compared to the narrowest plasma amplifiers studied previously and here.
