内容記述 |
A recombination plasma soft x-ray laser that is associated with Li-like aluminum ion was investigated to increase the gain coefficient. By optimizing the time interval of the 16-pulse train, higher-density plasma with a low temperature could be generated, and thus, we obtained the gain coefficient of 9.84 cm?1 at the pump laser pulse energy which was as low as 3 J. To further enhance the x-ray laser output energy, the single resonator which was installed by using a Mo/Si multilayer mirror that has a high reflectivity of 0.45 at 15.5 nm, and the x-ray spectrum after the double pass in the lasing medium was measured. As a result, the output intensity was increased to be 1.5 times higher than that when it was compared with those that were conducted with no X-ray mirror. |
