Optimisation of Transient Gain X-ray Laser for 20-32 nm: TMR Large-ScaleFacilities Access Programme

摘要

The development of X-ray lasers is market by the progression toward shorterwavelengths using less drive energy. A recent X-ray laser experiment at the Rutherford Appleton Laboratory demonstrated saturated X-ray laser operation in the Ne-like Ti and Ge X-ray laser schemes at 32.6 and 19.6 nm respectively, with a drive energy of only a few joules, a significant step in the progression to table top systems. In this report the authors describe the laser development necessary to generate suitable travelling wave line-focus laser drive pulses and the transient population inversion X-ray laser results obtained.
