| Abstract: | The current saturated operation of X-ray lasers at wavelengths > 15 nm requires at least kilojoule drive energy, which is only available at the largest laser installations in the world. Using a specially designed drive pulse configuration, saturated operation of a Ni-like Sn X-ray laser at 12 nm has been achieved with only 75 J drive energy. An efficiency as high as 9 × 106 in converting laser energy from the 1 eV optical spectral range to the 100 eV soft X-ray range has been reached. This paves the way for applications of saturated X-ray lasers at 12 nm at many other smaller laboratories. |
