Modleing of psec laser driven Ne-like and Ni-like x-ray lasers
This paper models recent experiments in which a solid titanium target was illuminated by several joules of combined energy from a nsec laser pulse to create a preplasma followed by a psec laser pulse to drive the gain. Gains greater than 200 cm{sup -1} are predicted for the Ne-like Ti 3p {sup 1}S{sub 0} {yields} 3s {sup 1}P{sub 1} transition at 32.6 nm which is driven by the monopole collisional excitation. High gain is also predicted for the 3d {sup 1}P{sub 1} {yields} 3p {sup 1}P{sub 1} transition at 30.1 nm which is driven by a combination of collisional excitation and self photopumping. We also discuss the possibilities for driving a Ne-like Ge laser using this approach. For the Ni-like ions we model a solid molybdenum target under similar conditions used for Ti and predict gains greater than 300 cm{sup -1} for the Ni-like Mo 4d {sup 1}S{sub 0} {yields} 4p {sup 1}P{sub 1} transition at 18.9 nm which is driven by the monopole collisional excitation. High gain is also predicted for a self photopumped 4f {sup 1}P{sub 1} {yields} 4d {sup 1}P{sub 1} transition at 22.0 nm and several other transitions driven by inner shell collisional ionization.
