Rep-rated high-energy laser

罗斯托克大学物理研究所将采购和安装一台高能激光系统，提供~10J的脉冲能量，脉冲宽度为~10 ns，重复频率为&gt；1 Hz，以在实验室产生~100 Gpa的动态压缩压力。这将允许开发和测试新的动态压缩样品环境，用于在欧洲XFEL等大型用户设施进行实验，以研究行星内部条件下的结构转变和化学反应。此外，激光系统将用于系统地探索在极端压力和温度环境下创建的有趣材料结构的释放物理，以便在环境条件下潜在地保持亚稳定。一个特别有趣的例子是有控制地产生特定色心和大小远低于10纳米的钻石纳米颗粒。

A high-energy laser system providing pulse energies of ~10 J in pulse durations of ~10 ns at repetition rates of > 1 Hz will be procured and installed at the Institute of Physics of University of Rostock to create dynamic compression pressures of ~100 GPa in the laboratory. This will allow for developing and testing novel dynamic compression sample environments for experiments at large-scale user facilities such as European XFEL to investigate structural transitions and chemical reactions at planetary interior conditions. In addition, the laser system will be used to systematically explore the release physics of interesting material structures created at extreme pressure and temperature environments to potentially remain metastable at ambient conditions. A particularly interesting example is the controlled generation of diamond nanoparticles with specific colour centres and sizes well below 10 nm.
