High-energy 4{omega} probe laser for laser-plasma experiments at Nova
- L-399, Lawrence Livermore National Laboratory, University of California, Livermore, California 94551 (United States)
For the characterization of inertial confinement fusion plasmas, we implemented a high-energy 4{omega} probe laser at the Nova laser facility. A total energy of {gt}50 J at 4{omega}, a focal spot size of order 100 {mu}m, and a pointing accuracy of 100 {mu}m was demonstrated for target shots. This laser provides intensities of up to 3{times}10{sup 14}thinspWthinspcm{sup {minus}2} and therefore fulfills high-power requirements for laser-plasma interaction experiments. The 4{omega} probe laser is now routinely used for Thomson scattering. Successful experiments were performed in gas-filled hohlraums at electron densities of n{sub e}{gt}2{times}10{sup 21}thinspcm{sup {minus}3} which represents the highest density plasma so far being diagnosed with Thomson scattering. {copyright} {ital 1999 American Institute of Physics.}
