Optical spectroscopy provides extraordinary insights on the electronic structure of materials and their properties. It has been and continues to be a major driving force in the development of low-dimensional materials by enabling a rigorous understanding of quantum processes and interactions and by guiding their implementation in electronic and optoelectronic applications ranging from energy conversion to solid-state lighting. In recent years, our team composed of three spectroscopists has made seminal contributions in the optical control of quantum states in semiconductors, the development of devices operating in the ultrastrong light-matter coupling regime, the measurement of electric fields in the THz (including that of the vacuum), and the development of tools and methods for precision spectroscopy. To support these activities as wells as new ones, our team requests a highly needed continuous-wave narrow-linewidth tunable Ti:S equipped with a frequency doubler. Currently unavailable at Polytechnique, this important spectroscopy tool will enable high-resolution spectroscopy on impurity defects, quantum dots, and other low-dimensional structures and reveal critical information on electronic states, their environment, the emergence of collective phenomena, and their interactions with low-energy excitations. Furthermore, this laser will provide the means to address several outstanding opportunities in the field of quantum optics: efficient spin-photon interfaces, laser cooling in the quantum regime, and quantum spectroscopy techniques promising to revolutionize our ability to measure atomic, molecular, solid-state, and biological systems. By enabling research of the highest caliber at the forefront in quantum optics, this instrument will serve to further enhance Canada's research competitiveness and play an important role in attracting and training HQP of the highest quality.

光谱学提供了有关材料及其性能的电子结构的非凡见解。通过对量子过程和相互作用的严格了解，并指导其在电子和光电的应用中实施，从能量转换到固态照明，它一直并继续成为低维材料开发的主要动力。近年来，由三位光谱学家组成的团队在半导体中的量子状态，在超局部光线耦合方案中运行的设备的开发，在THZ中测量电场（包括真空的电场）以及精确光谱的工具和方法的开发。为了支持这些活动和新活动，我们的团队要求配备了频率加倍的急需连续的波窄线可调ti：S。目前，这种重要的光谱工具目前无法在理工中获得，将使高分辨率的光谱对杂质缺陷，量子点和其他低维度结构进行高分辨率，并揭示有关电子状态，其环境，集体现象的出现以及它们与低邻里兴奋的相互作用的关键信息。此外，该激光器将提供解决量子光学领域的几个出色机会的手段：有效的自旋光子接口，量子状态中的激光冷却以及量子光谱技术，希望彻底改变我们测量原子，分子，固态，固态和生物系统的能力。通过在量子光学方面对最高口径的最高口径进行研究，该工具将进一步增强加拿大的研究竞争力，并在吸引和训练最高质量的HQP中发挥重要作用。
