Ultrafast laser science has had, and continues to have enormous impact in multiple areas of science and technology. This has clearly been reconfirmed by the recent Nobel Prize in Physics awarded to Prof. Donna Strickland and Prof. Gérard Mourou, "for their method of generating high-intensity, ultra-short optical pulses". The frontiers of ultrafast laser science have continued to expand over the past 30 years, and with it opening new areas of application, which started from basic physics and chemistry, and is now extending to many sectors of importance to Canada, such as energy, pharmaceutics and medicine. My past Discovery Grants have supported a research programme on Extreme Photon Science & Technology (EPST): the science of ultrafast photon sources with extreme characteristics (such as in terms of wavelength, peak intensity and pulse duration), and developing innovative technologies for various applications that take advantage of such unique photon sources. Research in EPST has significantly advanced over the years, especially in the X-ray range (high-order harmonic generation, HHG) and in the far-infrared (terahertz [THz] frequencies). Looking back, it turns out that my approaches to advance EPST have been rather atypical and unconventional, which at first sight might seem to contradict or counter common understandings. In many such cases, such Maverick approaches (with a twist) has led to unexpected outcomes, and in some cases opening up surprising and new opportunities, thus pushing forward the frontiers of EPST. The long-term goal of my research is to pioneer and advance Extreme Photon Science & Technology (EPST), to unravel new knowledge and to apply the research outputs to find solutions to challenges currently faced in various sectors of importance to Canada. To achieve this goal, I propose to further deepen our understandings of the findings obtained from the atypical approaches of my past Discovery grants, as well as to design and study new techniques in EPST with a twist. To this end, the mid-term objectives of the proposed Discovery Grant is (i) to study the interaction of intense THz radiation with various materials (such as DNA, semiconductors and graphene) at unprecedented THz fields and repetition rates, and elucidate their mechanisms; (ii) to study the ultrafast dynamics of autoionizing states via high-order harmonic spectroscopy using HHG from laser ablation plume of various materials; (iii) to develop novel techniques to improve and modify a unique equipment, the THz Chemical Microscope, and apply them for studies in various sectors, such as cancer research, tick-borne disease detection and the treatment of algal toxins. Outcomes of this Discovery programme should not only advance our knowledge, but may also result in innovative methods to detect and monitor metastatic cancer, diagnose Lyme disease, and provide novel methods to control toxins produced by bacteria, which may pollute our water source.

Ultrafast激光科学对诺贝尔·斯特里克兰（Donna Strickland）教授和吉拉德·穆鲁（GérardMourou）教授的最新诺贝尔物理学奖对多个科学和技术领域产生了巨大影响脉搏”。在过去的30年中，超快激光科学的前沿一直在扩展，它开发了新的应用领域，这些领域从基础和化学开始，现在一直延伸到许多对加拿大重要性的领域，例如能源，药物和医学。多年来，EPST的研究已经显着进步，尤其是在X射线范围（高阶谐波生成，HHG）和远红外（频率）中，事实证明我的进步Epst的方法相当乍看之下，这可能与这种特立独行的方法相矛盾 - 我的研究的期限是开拓和促进极端的光子科学与技术（EPST），揭示新知识，并为了找到对加拿大重要性而面对的解决方案。为了进一步加深我们对从我过去的发现赠款的非典型方法获得的发现的理解，关于设计和研究新技术是（i）是（i）研究强烈THZ辐射与各种材料的相互作用（例如DNA，半导体和半导体和半导体，石墨烯在前所未有的THZ领域和重复速率上，并通过高阶谐波光谱使用HHG使用来自各种肥料的材料（III）来开发新技术，以改善雄性设备，例如，癌症研究，壁虱传播疾病检测和藻类的治疗不仅应提高我们的知识，而且还可能导致创新的方法检测和监测转移性癌污染我们的水源。
