A 10-ps, 263-nm (4ω) laser is being built to probe plasmas produced on the OMEGA EP. A suite of optical diagnostics (schlieren, interferometry, and grid image refractometry) has been designed to diagnose and characterize a wide variety of plasmas. Light scattered by the probe beam is collected by an f/4 catadioptric telescope and a transport system is designed to image with a near-diffraction-limited resolution (~1 - μm full width at half maximum) over a 5-mm field of view to a diagnostic table. The transport system provides a contrast greater than 1 : 10⁴ with respect to all wavelengths outside of the 263 ± 2 nm measurement range.
