A system based on using soft X-rays from laser-produced plasmas to photoionize atomic vapors is proposed to produce population inversion and lasing on a 3s → 2p transition of Mg II at 24.7 nm. The processes by which inversion is produced are described. Predicted gains have been calculated using a rate equation model that describes the processes in a traveling-wave geometry. Other processes considered in the theoretical model include ionization and inelastic collisions with electrons and, more importantly, recombination. Assuming that half of the Mg vapor can be preexcited at 10 torr, an amplification of exp(20) should be possible with a 10-J (200-ps FWHM) 1064-nm laser focused onto a tantalum target as a pump source.
