The Nobel Prize winning technology of Chirped Pulse Amplification (CPA) invented by Prof. Donna Strickland and Prof. Gérard Mourou in 1985 has revolutionized laser-plasma physics through the realization of laboratory-scale laser systems capable of producing high power, femtosecond duration pulses. Such extreme levels of peak power have led to a new generation of bright particle and radiation sources over a broad spectrum of energies and wavelengths, each inheriting femtosecond-scale duration from the driving laser pulse. CPA laser systems can also be used to drive matter into extreme states of temperature and pressure, mimicking those typically found in astrophysical environments, and leading to the observation of new and exotic states of matter on Earth. Understanding the properties and generation of this matter is an essential component of describing the conditions of stellar interiors, including our Sun, and for the development of controlled fusion-energy devices. However, an accurate description of these exotic states remains an experimental and theoretical challenge, significantly complicated by its highly transient nature, requiring experimental diagnostics capable of resolving dynamic processes on the ultra-fast (picosecond-femtosecond) timescale. The proposed research program pursues advanced understanding of high-energy-density states of matter through first-of-their-kind high spectral and temporal resolution experiments, and works toward a new generation of ultrafast probes and inspection techniques using laser-driven particle beams, X-rays and infrared sources to put Canadian research centers and industries at the forefront of laser-based innovations. Further, these advanced laser technologies can be used to develop affordable, flexible and compact multi-MeV electron, proton and gamma-ray radiation sources suitable for medical treatments and applications. This research will provide unique opportunities for the training of highly qualified personnel through regular hands-on experiments with high-intensity laser experimental facilities at the University of Alberta and international collaborations on large-scale laser systems around the world.

1985年，由Donna Strickland教授和GérardMourou教授发明的诺贝尔奖获奖技术（CPA）通过实现了能够产生高力量，femtoctocteent utatration Pulses的实验室尺度激光系统，彻底改变了激光 - 播种机物理学。这种极端的峰值功率导致了新一代的明亮粒子和辐射源，并在各种能量和波长上，每种都从驱动激光脉冲中遗传了飞秒尺度的持续时间。 CPA激光系统也可以用来将物质推向温度和压力的极端状态，模仿通常在天体物理环境中发现的物质，并导致观察到地球上新物质的新状态。了解此问题的特性和生成是描述包括我们的太阳在内的恒星内部条件以及受控融合能源设备的开发的重要组成部分。然而，对这些异国情调状态的准确描述仍然是一个实验性和理论挑战，其高度瞬时性质显着复杂，需要能够在超快速（picsecond-femtsecond）时期解决动态过程的实验诊断。拟议的研究计划通过首先使用的高光谱和临时分辨率实验来追求对物质高能密度状态的深入了解，并致力于使用激光驱动的粒子梁，X射线和红外线来实现新一代的超快问题和检验技术，以使加拿大研究中心和工业公司成为Lasevations of Lasersey Innovations Innovations Innovations Insovations。此外，这些先进的激光技术可用于开发负担得起，柔性和紧凑的多MEV电子，质子和伽马射线辐射源，适用于医疗治疗和应用。这项研究将通过常规的动手实验为培训高素质的人员提供独特的机会，并在艾伯塔大学（University of Alberta University）进行高强度激光实验设施以及全球大型激光系统的国际合作。
