Abstract
The theoretical study and computational simulation of soft X-ray laser produced by the recombination of highly ionized plasma are given. An one-dimensional non LTE radiative hydrodynamic code JB-19 is used for simulating the process of soft X-ray laser produced by the recombination. The incident laser light is focused linearly onto the thin carbon fibre. In the duration of incident laser pulse a highly ionized plasma is generated. After the incident laser has been ended the plasma adiabatically expands and rapidly cools down. During the time of three-body recombination and cascading transition, the population inversion between n = 3 and n = 2 is produced and transition gain is obtained. The analysis and evolution is presented, and factors effected on the gain are also discussed. The calculated results have been compared with the experimental data of RAL. It is found that some were in good agreement with them but some are not. Under the limitation of laser energy, the gain is inversely proportional to the wave-length and pulse width of incident laser. For obtaining high gain it is necessary to have double frequency and to shorten the pulse width of Nd-glass laser. Finally the preliminary results about H-like F ion are
