Russia Marks 81 Years Since the Birth of Its Nuclear Industry: From the Soviet Nuclear Program to Modern Nuclear Talent Development

On August 20, 1945, the founding documents establishing the Special Committee and the First Main Directorate under the Council of People's Commissars of the USSR were officially signed, generally regarded as the starting point of the Soviet nuclear industry system. Eighty-one years later, Russia's nuclear energy community once again looks back at this historical milestone, linking it to nuclear science and technology development and talent cultivation. In August of that year, after the United States used atomic bombs on Hiroshima and Nagasaki, the Soviet Union accelerated the establishment of its own nuclear research and industrial system. On August 29, 1949, the Soviet Union completed the RDS-1 nuclear test. Thereafter, Soviet nuclear science gradually extended from military applications to peaceful uses, building the world's first grid-connected nuclear power plant and developing a fleet of nuclear-powered icebreakers.

U.S. SYNOPTICS Produces Large-Size Yb:YLF Crystal for Inertial Confinement Fusion Laser Systems

On August 19, SYNOPTICS, a subsidiary of Northrop Grumman, announced that it had successfully grown and harvested a large-size ytterbium-doped yttrium lithium fluoride crystal, namely a Yb:YLF crystal ingot. The crystal measures approximately 127 millimeters at its widest point, with a diameter three times the industry standard. SYNOPTICS stated that as laser engineering continues to expand toward higher efficiency and higher power, the demand for gain media with larger apertures and larger dimensions continues to grow. The Yb:YLF crystal produced this time is approximately 20% larger than the largest crystal the company had previously grown, and approximately 50% larger than the company's conventional product size. Kevin Stevens, General Manager of SYNOPTICS, stated that yttrium lithium fluoride is a commonly used host material for laser-active rare-earth ions, and scaling up the growth of YLF crystals will help laser engineers continue to raise the upper limit of achievable laser output power. He said that such materials are of significant importance for applications including directed energy, inertial confinement fusion, and industrial laser systems. Stevens also stated that Yb:YLF crystals can be used in applications requiring reduced thermal lensing effects and enhanced pulsed energy storage capability, while also leveraging their natural birefringent host to achieve polarization characteristics. According to information recently released by SYNOPTICS, some of the crystals will be used in the high-energy laser system at the German Electron Synchrotron Research Center (DESY) to support its inertial confinement fusion energy research. The company is currently studying the feasibility of further scaling up the size of Yb:YLF crystals, and plans to extend the relevant processes to other rare-earth-ion-doped YLF crystals, including holmium, thulium, and neodymium doping systems.
