pulses are now generated by the addition of a new front end, another amplifier, and a vacuum compressor. The optical pulse length at various points in the beam path is noted.
The south target chamber supports material dynamics experiments with a wide array of diagnostics. Primary among them are the transient imaging displacement interferometry for two-dimensional surface displacement measurements and VISARs, both point and line. Several different types of targets are used, as shown at the right.
The south target chamber also supports innovative laser-plasma interaction experiments using long-pulse beams to form plasma from a gas-jet source and a interaction pulse. Backscattered energy and spectral diagnostics measure both stimulated Brillouin and Raman scattering. A transmitted beam diagnostic records how the plasma affects the interaction beam.
The north target chamber enables short-pulse experiments using an off-axis parabola to focus the beam coming from the vacuum pulse compressor (at left). Diagnostics include beam diagnostics such as focal spot size. The primary target interaction diagnostics are the RCF stacks and MeV spectrometer, as well as x-ray imaging and spectroscopic instruments.
