密歇根大学研究人员开发了一种简单有效的方法来生产浓缩同位素膜。此法用台式太瓦激光器 ,提供一个简洁方法来替换传统的气体扩散技术。一台 780 nm的钛宝石啁啾脉冲放大激光器用超短高能脉冲烧蚀一固体靶。扩张的等离子体使较轻的同位素位于其中心 ,较重同位素则呈螺旋形分布 Researchers at the University of Michigan have developed a simple and efficient way to produce concentrated isotope membranes. This method uses a desktop terabit lasers to provide a concise way to replace the traditional gas diffusion technology. A 780 nm Ti: sapphire chirped pulse amplification laser ablates a solid target with ultrashort high energy pulses. The expanded plasma places the lighter isotope in its center and the heavier isotope in a spiral distribution
