On May 26, 2020 the Multi-Terawatt (MTW) Laser operational team celebrated their 10,000th laser shot. The first shot on the MTW laser, a midscale system built initially as the prototype front end for OMEGA EP, was taken in 2004. Since that time, a compression chamber along with three target chambers have been added, the maximum energy was increased, and the temporal contrast improved, making MTW a complete facility for plasma-physics research, laser technology development, and target diagnostic development. External and internal users have carried out 535 campaigns on MTW, using pulse durations from 500 fs to 2.8 ns, energies up to 120 J, and wavelengths centered at 1053 nm or 2~, 4~, and 5~ harmonics. The milestone shot was taken in support of an external campaign for L3Harris Technologies (L3H), a global aerospace and defense technology company with local roots. Two-color, laser-shearing interferometry (see inset) is used to infer spatially resolved density profiles within the ablation plume and to monitor plasma expansion into a low-density background gas. The inset image was taken during the 10,000th shot.
