title: Two-photon resonances in Xe and Kr for the generation of tunable coherent extreme UV radiation.
abstract: Using eleven two-photon resonances in Xe and Kr, a comparative study of the resonant third harmonic generation and saturation properties in the 70.9-75.5-nm extreme ultraviolet (XUV) region was made. The fundamental deep ultraviolet radiation was produced in a nonlinear crystal beta-BaB(2)O(4). The two-photon resonances 5p-6p'[1/2](0) and 8p[1/2](0) in Xe, as well as the 4p-5p[1/2](0) and [5/2](2) resonances in Kr, are useful for efficient tunable XUV generation in the 71-92-nm region.
