Abstract
The use of mixed gases of working atoms with a much higher density of hydrogen has been proposed in recombination type x-ray lasers excited by high-intensity ultrashort pulse lasers. Hydrogen was chosen as the most suitable material to supply low-energy electrons in the optical-f ield ionization. Numerical analysis shows that a maximum gain can be e xpected for lithiumlike neon at a relatively low neon density of 9x10( 17) cm(-3) with 60 times higher hydrogen density. [S1050-2947(97)09811 -9].
