Abstract

Summary form only given. The 60-beam OMEGA laser is used for inertial confinement fusion (ICF) studies. OMEGA is a solid-state glass laser, frequency tripled to deliver 351-nm light to ICF targets. To achieve the highest compression of the ICF target, it is necessary to tailor the shape of the optical pulse; which drives the implosion. Pulse-shaping and pulse-propagation codes have been implemented on OMEGA over the past four years; however, we have recently upgraded the pulse-shape diagnostics at both the input and the output of the system with multichannel streak cameras. One of these cameras measures the IR pulse shape at the input of the, OMEGA amplifier chain for each of the three driver regenerative amplifiers, which can be used to seed the amplifier chains.
