Thermal beam distortions in end-pumped Nd:YAG, Nd:GSGG, and Nd:YLF rods

IEEE Journal of Quantum Electronics (1994)

C. Pfistner Rudolf Weber H. P. Weber S. Merazzi R. Gruber

The thermally induced beam distortions in end-pumped Nd:YAG, Nd:GSGG, and Nd:YLF rods were analyzed and the influence of edge- and face-cooling was investigated. The distributions of temperature, stress, and strain in the crystals were calculated by finite element analysis. Based on these data, the space-resolved changes of the refractive index were determined considering thermal dispersion, surface deformation, and strain-induced birefringence. The resulting optical path difference for one round-trip in the end-pumped rods was integrated numerically. For each rod, the induced thermal lens was determined over the extent of the pump spot radius. The calculations of the optical path difference were experimentally confirmed by investigations using a modified Twyman-Green interferometer with a polarized HeNe probe beam at 633 nm under lasing and nonlasing conditions.< >

The Terpsichore Code for the Stability Analysis of Magnetically Confined Fusion Plasmas

David V. Anderson W.A. Cooper R. Gruber S. Merazzi U. Schwenn

We describe a few relevant aspects of the new plasma physics stability code, TERPSICHORE, which breaks new ground both in plasma theory and in its algorithmic implementation. We chose a highly accurate discrete mathematical representation which led to the choice of algorithms that matched the vector-parallel architecture of the Cray Y-MP and Cray-2 supercomputers quite well. The resulting code runs at Gflop/s speeds, which translates into a very high efficiency. This means we can perform very extensive studies within our limited computer budgets.
