Abstract
The intensity distribution on a fusion target is an important quantity in understanding the performance of ICF targets. The extremely high intensity at the focus of the Nova laser and the geometry of the ten frequency-converted Nova laser beams have required a new approach to recording the far-field spatial and temporal intensity distribution, A diagnostic package to characterize the focal plane on Nova, known as the opposed part diagnostic (OPD), was developed for Nova. The OPD uses an inverse Cassegrain design to image the target plane of Nova from a port opposite the irradiating beam to be characterized.
