The recombination pumping scheme for soft X-Ray lasers has better energy scaling, than the collisional-excitation pumping scheme. Implementation of an H-like 3→2 Nitrogen recombination laser, at »∼13.4nm requires initial conditions of at least 50% fully stripped Nitrogen, kTe∼140eV and electron density of ∼1020cm−3. In order to reach population inversion, the plasma cooling to below 60eV should be...
The recombination pumping scheme for soft X-Ray lasers has better energy scaling, than the collisional-excitation pumping scheme. Implementation of an H-like 3 → 2 Nitrogen recombination laser, at λ∼13.4 nm requires initial conditions of at least 50% fully stripped Nitrogen, kTe∼140eV and ne∼1020cm−3. In order to reach population inversion, the plasma cooling to below 60eV should be faster than the...
Summary form only given. A recombination based X-ray laser has a preferred energy scaling compared to the collisional ionization scheme. Implementing a nitrogen recombination laser at lambda~13.4 nm, requires a confined plasma initially at Te~140 eV and Ne~1020 cm-3 to be rapidly cooled to Te<60 eV. The cooling time scale should be shorter than the 3-body recombination time scale of 3-6 ns. The...
