The advantages of short wave-length radiation for laser fusion in terms of laser absorption and low levels of suprathermal electron preheat are well known. Recently, these have been characterized for 6 beam 351 nm irradiation on solid spherical targets. In this report, we extend these studies to imploding shell targets driven by 6 or 12 beams from the OMEGA laser system. With these targets, the critical density surface is expected to move toward the target center during the laser pulse, reducing the absorption. The measurements will be compared to the predictions of hydrodynamic code calculations.
