Lawrence Livermore National Laboratory soft x-ray laser program
The Laboratory soft x-ray laser program at the Lawrence Livermore National Laboratory's Nova laser facility has been pursuing soft x-ray laser research with the goal of developing x-ray laser physics and the necessary technology for producing usable x-ray lasers. For the microscopy community, this means developing short wavelength (lambda < 44 A), high power (10/sup 8/ W), highly coherent lasers to be used in microscopy and holography applications. Significant progress toward this goal has been achieved. A variety of x-ray lasers based on the collisional pumped Ne-like laser scheme have been developed and characterized in great detail. A new collisionally pumped laser utilizing Ni-like ions has been demonstrated with laser wavelengths as short as 50 A. This new scheme is scalable to sub 44 A wavelengths. Preliminary ionization balance experiments have also begun for recombination pumped lasers which should also readily scale to sub 44 A wavelengths. A laser cavity has been developed and demonstrated using multi-layer x-ray mirrors and beam-splitters. This offers the possibility of improved laser coherence and efficiency. An applications beamline was constructed and used in a photoionization physics experiment in conjunction with Bell Laboratory. This was an important demonstration of the ability to make existing x-ray lasers usable and available for the general science community. Finally, x-ray holography using an x-ray laser has been demonstrated. 16 refs., 4 figs.
