Rep-rated high-energy laser

在罗斯托克大学物理研究所将获得一个高能激光系统，该系统提供的脉冲能量为~ 10j，脉冲持续时间为~ 10ns，重复频率为bbbb1hz，可在实验室中产生~ 100gpa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，用于大型用户设施（如欧洲XFEL）的实验，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产生的有趣材料结构的释放物理学，以潜在地在环境条件下保持亚稳态。一个特别有趣的例子是控制生成具有特定色心且尺寸远低于10纳米的金刚石纳米颗粒。

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.
