项目摘要

"Science is a Pipeline" is the concept that more often than not it's basic curiosity-driven discovery research that supplies the ideas, the understanding, and the concepts which eventually make their way into innovation, commercial impact and social benefits. My research, with my team members, begins with the science of the interaction between extremely short pulses of intense laser light and matter. At its most basic, I'm interested in how the relationships between light and matter change -- qualitatively, fundamentally -- in the case of the most intense light anyone can produce on Earth. The things we learn, and the techniques and tools we develop along the way, we're then able to use towards creative innovations. My team and I have taken new physics-knowledge we've developed, and used it as a foundation to invent new kinds of laser materials-processing. We've also used the new science we've found in laser materials-processing to create new and less-invasive ways to do arthroscopic knee surgery, using rapid trains of very short pulses. Ultra-intense laser-matter interaction: My most basic and curiosity-driven physics, needs access to the highest-intensity lasers worldwide, taking opportunities in France, the UK, and the USA, as well as at home. Our theoretical work needs access to extremely powerful multi-processor computers to run simulations, though we also work some problems with pen and paper. For some years, this has made contributions in atomic physics, nonlinear optics, relativistic laser-plasma physics and astrophysics. It has also provided the foundations of my commercially significant applied-physics research. Applications of ultrashort-pulse intense optical physics: This foundational science program always very closely informs the applied-physics research I do, closer to home. We use the same kind of ultrafast lasers, but not scaled to the world's highest optical intensities. These lasers, of the same basic technology, we invent or buy and operate in my own laboratories. We consistently discover qualitatively new ways to 'treat' materials and biotissues: modifying structure, changing functionality, mitigating problems and creating new opportunities, new tools, new approaches. This gives students of all kinds -- and driven by different career goals -- an exceptional opportunity to develop their deep understanding in physics, medical biophysics and optics, while supporting the ambition of most to contribute to society in the most important ways they can imagine. What unifies all of these efforts -- what has created research projects funded by CHRP or NSERC-Strategic funding, led to NSERC-Engage and direct support from industrial partners, what has in turn benefitted from these other sources, and what also ties all of it together -- has been NSERC Discovery program funding.

“科学是一条管道”这一概念通常是由好奇心驱动的基本发现研究，提供最终转化为创新、商业影响和社会效益的想法、理解和概念。我和我的团队成员的研究始于强激光极短脉冲与物质之间相互作用的科学。最基本的是，我感兴趣的是在地球上任何人都能产生的最强烈的光的情况下，光和物质之间的关系如何从质上、根本上发生变化。我们学到的东西以及我们一路开发的技术和工具，然后我们就能够用于创造性的创新。我和我的团队采用了我们开发的新物理知识，并将其作为发明新型激光材料加工的基础。我们还利用在激光材料加工中发现的新科学，利用极短脉冲的快速序列，创造新的、侵入性较小的膝关节镜手术方法。超强激光与物质相互作用：我最基本和好奇心驱动的物理学，需要获得全球最高强度的激光，抓住法国、英国、美国以及国内的机会。我们的理论工作需要使用极其强大的多处理器计算机来运行模拟，尽管我们也用笔和纸来解决一些问题。多年来，它在原子物理学、非线性光学、相对论激光等离子体物理学和天体物理学方面做出了贡献。它还为我具有商业意义的应用物理研究奠定了基础。超短脉冲强光学物理的应用：这个基础科学项目总是为我所做的离家较近的应用物理研究提供非常密切的信息。我们使用相同类型的超快激光器，但未扩展到世界上最高的光学强度。这些激光器具有相同的基本技术，我们发明或购买并在我自己的实验室中操作。我们不断发现“处理”材料和生物组织的新方法：修改结构、改变功能、缓解问题以及创造新机会、新工具、新方法。这为各类受不同职业目标驱动的学生提供了一个绝佳的机会，让他们加深对物理学、医学生物物理学和光学的理解，同时支持大多数人以他们能想象到的最重要的方式为社会做出贡献的雄心壮志。是什么将所有这些努力统一起来——是什么创建了由 CHRP 或 NSERC 战略资助资助的研究项目，导致 NSERC-Engage 和工业合作伙伴的直接支持，什么反过来从这些其他来源中受益，以及什么也将所有这些联系在一起它一起——得到了 NSERC Discovery 计划的资助。 “Des chercheurs qui cherchent，on en trouve。Des chercheurs qui trouvent，on en cherche。” ——戴高乐
