超快激光将彻底改变物理学

作者:1,2,3,4,5 来源: 日期:2020-3-20 13:22:05 人气:25

在今天的《科学美国人》(Scientific American)杂志上,刚登载了一篇著名美籍华人科学家的专稿文章,标题为:“超快、超强的激光将彻底地改变物理学”。

在介绍这篇文章前,我们先简介文章作者、华人科学家。她名为塔米·马(Tammy Ma),自小随没机会读完高中的父母从加拿大移民到美国。2005年获得加州理工学院的航空工程学士学位,2008年获得硕士学位和博士学位。以后在美国能源部所属的国家研究机构——劳伦斯·利弗莫尔国家实验室完成博士后研究,并成为一名实验物理学家。最近获得总统科学与工程学早期职业奖,这是美国政府授予年青科学与工程专业人士最高荣誉,获得过美国物理学会Thomas H. Stix奖,以表彰在等离子体物理研究方面的杰出早期职业贡献。受邀作为嘉宾参加世界经济论坛。
她在文章中介绍:“不久前,我还在读研究生时,参加了我的第一个高强度激光等离子体实验。大约每隔一小时,高功率激光器将释放不到1万亿分之一秒长的能量,释放出1皮瓦的能量,这是整个美国电网提供的功率的100倍,聚焦到直径为直径的十分之一的点上,犹如一根人的头发,放在一个微小的金属箔靶上。”
