Paper Abstract

We describe our recent progress in the investigation of the spectral properties of collisional XUV lasers, including both experimental measurements and numerical calculations. Using a wavefront-division, variable path-difference interferometer, we have characterized the temporal coherence and the spectral width of an injection-seeded transient XUV laser emitted at 18.9 nm from a Ni-like Mo plasma. Our results show that the temporal coherence of the beam is significantly increased by the injection-seeded operation, compared to the standard ASE mode, in agreement with detailed numerical simulations. Using the PPP code we have calculated the intrinsic linewidth of the same lasing line over a range of electron density and at temperatures that are relevant to transient collisional pumping. We discuss the relative contributions of homogeneous and inhomogeneous broadening to the overall profile.
