THz imaging constitutes one of the principal research directions of Prof. Skorobogatiy Canada Research Chair I in Ubiquitous THz photonics. Replacement of the failing femtosecond laser is absolutely essential for the success of his internationally recognized research program in THz imaging. The failing pump laser makes the core of Prof. Skorobogatiy THz imaging laboratory and further progress of his group in this vibrant field will be impossible without replacement of the above-mentioned equipment. Over the past 5 years Prof. Skorobogatiy has developed a world class highly publicized and innovative research program in THz imaging that resulted in many high-impact publications, discovery of new imaging techniques, and pursuit of several commercialization opportunities. The imminent failure of the pump laser comes at a critical time for his group that is currently transitioning from the THz imaging demonstrators to an industrial-strength real-time super-resolution spectroscopic microscopy system. Such systems can have a significant impact on various applied fields including biomedical imaging and diagnostics, non-destructive quality control and monitoring, as well security and environmental industries. More specifically, the requested laser is in the core of Prof. Skorobogatiy effort in THz super-resolution solid immersion spectral microscopy. Together with advanced solid immersion lens designs (using high dielectric index materials and metamaterials), as well as advanced instrumentation (fast rotary delay lines, non-mechanical beam steering), he aims at realizing record-breaking THz microscopes in terms of spatial and spectral resolutions, as well as image acquisition time. The application of such microscopes are limitless with the most recent demonstrations from Prof. Skorobogatiy and his collaborators being in cancer margin discrimination in live tissues, as well as direct measurement of material complex dielectric constant with deeply subwavelength spatial resolution. Last, but not least, mentoring opportunities related to the use of the requested equipment will provide a high-quality training environment by promoting multidisciplinary projects of high socio-economic impact within a collaborative training environment. Multidisciplinary will ensure that HQPs in training will learn and practice a variety of the state-of-the-art techniques using world-class infrastructure for THz spectroscopy and imaging, as well as additive manufacturing and advanced material synthesis. Collaborative training environment is ensured by the extensive international network of researchers participating in the research program. Finally, socio-economic impact of conducted research is expected to be high, with trained HQPs able to market their skills immediately upon graduation. This is because the domains of material's characterization, as well as industrial and medical imaging are in rapid development all over the world, and Canada and Quebec, in particular.

THZ成像构成了加拿大Skorobogatiy Canada教授研究主席I的主要研究指示之一。替换失败的飞秒激光器对于他在THZ成像中获得国际认可的研究计划的成功绝对至关重要。失败的泵激光使Skorobogatiy Thz成像实验室教授的核心和他组在这个充满活力的领域的进一步进展将是不可能的，而如果不替换上述设备。在过去的5年中，Skorobogatiy教授在THZ成像中开发了一项世界一流的高度宣传和创新的研究计划，导致许多高影响力出版物，发现新成像技术以及追求几种商业化机会。泵激光器的迫在眉睫的失败是在他的组中的关键时刻，目前正在从THZ成像示威者过渡到工业强度实时的实时超分辨率光谱显微镜系统。这样的系统可能会对各种应用领域产生重大影响，包括生物医学成像和诊​​断，非破坏性质量控制和监控以及安全和环境行业。更具体地说，所需的激光是THZ超分辨率固体浸入光谱显微镜的Skorobogati努力的核心。与先进的固体浸入式镜头设计（使用高介电指数材料和超材料）以及先进的仪器（快速旋转延迟线，非机电束转向）一起，他的目的是在空间和光谱上实现创纪录的THZ显微镜分辨率以及图像获取时间。这种显微镜的应用是无限的，因为Skorobogatiy教授及其合作者的最新演示是在活组织中进行癌症边缘歧视，并直接测量具有深层次波长空间分辨率的材料复杂介电常数。最后但并非最不重要的一点是，与所请求的设备有关的指导机会将通过在协作培训环境中促进具有高社会经济影响的多学科项目来提供高质量的培训环境。多学科将确保培训中的HQP将使用世界一流的基础架构来学习和练习各种最先进的技术，以进行THZ光谱和成像，以及添加剂制造和高级材料合成。参与研究计划的广泛的国际研究人员网络确保了协作培训环境。最后，预计进行研究的社会经济影响将很高，受过训练的HQP能够在毕业后立即推销其技能。这是因为材料的特征领域以及工业和医学成像尤其是加拿大和魁北克的快速发展。
