While KDP and DKDP crystals remain the only viable solution for frequency conversion in large aperture laser systems in the foreseeable future, our understanding of damage behavior in the presence of multiple colors is very limited. Such conditions exist during normal operation where, for third harmonic generation, 1{omega}, 2{omega} and 3{omega} components are present with different energy ratios as they propagate inside the crystal. The objective of this work is to shed light into the damage behavior of frequency conversion crystals during operational conditions as well as probe the fundamental mechanisms of damage initiation. We have performed a series of experiments to quantify the damage performance of pristine (unconditioned) DKDP material under simultaneous exposure to 2{omega} and 3{omega} laser pulses from a 3-ns Nd:YAG laser system as a function of the laser influences at each frequency. Results show that simultaneous dual wavelength exposure leads to a much larger damage density as compared to the total damage resulting from separate exposure at each wavelength. Furthermore, under such excitation conditions, the damage performance is directly related to and can be predicted from the damage behavior of the crystal at each wavelength separately while the mechanism and type of defects responsible for damage …

Synchrotron-based methods have been developed at Lawrence Livermore National Laboratory (LLNL) for the direct observation of microstructure evolution during welding. These techniques, known as spatially resolved (SRXRD) and time resolved (TRXRD) x-ray diffraction, allow in-situ experiments to be performed during welding and provide direct observations of high temperature phases that form under the intense thermal cycles that occur. This paper presents observations of microstructural evolution that occur during the welding of a medium carbon AISI 1045 steel, using SRXRD to map the phases that are present during welding, and TRXRD to dynamically observe transformations during rapid heating and cooling. SRXRD was further used to determine the influence of welding heat input on the size of the high temperature austenite region, and the time required to completely homogenize this region during welding. These data can be used to determine the kinetics of phase transformations under the steep thermal gradients of welds, as well as benchmark and verify phase transformation models.

Transcript of an oral interview with Harold Tatsch. Prior to enlisting in the Navy, Tatsch worked as a bellhop in the Nimitz Hotel in Fredericksburg, Texas. In November, 1944, Tatsch joined the Navy. After completing training, Tatsch went aboard the USS Drexler (DD-741) where he served as an ammunition handler for a 40mm antiaircraft gun. Eventually, the Drexler made its way to Ulithi where it joined the armada headed for Okinawa. Tatsch also describes being on picket duty off Okinawa and being attacked by Japanese aircraft. On 28 May 1945, the Drexler was hit by two kamikazes and Tatsch describes the impacts and aftermath. He abandoned ship and spent about three hours in the water before being rescued. He was sent back to the US on a 40-day survivor leave. At the end of it, Tatsch re-enlisted, requesting more duty aboard destoryers. In the meantime, the war ended and he was shipped to Guam where he spent 18 months as a shore patrolman. When that was complete, Tatsch was discharged.
