Lasers and broadband optical sources operating in the deep UV are used extensively in research anddevelopment, as well as in many fields and applications, e.g., manufacturing, medical, and instrumentation.While existing products and solutions, e.g., combining solid state lasers operating in the IR with nonlinearfrequency conversion, can satisfy different demands, they often involve bulk implementations which createschallenges for achieving ultra-compact, rugged, and low cost units. Thus, there is growing interest in usingYb-doped fiber lasers to replace solid state lasers due to their ideal pulse and beam characteristics and availableoutput power; moreover, using a fiber gain medium allows for room temperature operation with no specificcooling requirements, thereby reducing power consumption. There has also been recent interest in developingdeep UV sources based on supercontinuum (SC) generation in gas-filled hollow-core photonic crystal fibers(HC-PCFs). Such approaches offer the advantage of simplifying implementation and packaging.This project builds on existing collaborations between McGill University and O/E Land Inc. and focuses ondeveloping ultra-compact, low cost, and high-power deep UV sources with high stability, high efficiency, andexcellent beam quality. Two main R&D thrusts will be explored: (1) optimizing optical systems formaximizing the efficiency of nonlinear frequency conversion and (2) deep UV generation via gas-filledHC-PCFs. A successful project outcome will allow O/E Land to develop new lasers and sources to address atechnology gap, diversify their product portfolio, and give them a competitive advantage in meeting theirclients' needs. Training will provide HQP with opportunities to develop technical knowledge and improvetheir ability to solve complex problems and perform critical analysis; skills which are sought highly in thebroad photonics sector and employers including optical component and instrumentation suppliers such as MPBCommunications (Montreal, QC), QPS Photronics (Montreal, QC), and OZ Optics (Ottawa, ON).

在研究和开发中以及在许多领域和应用中，例如制造，医疗和仪器，在深紫外线运行的激光器和宽带光学源都广泛使用。当现有的产品和解决方案中，例如，将在IR中运行的固体激光器与非线性转换相结合，以使其与非线性转换相结合，这些固体激光器可以满足范围，从而可以满足范围，从而可以满足范围的范围，从而使其实现了繁殖的繁殖范围，超紧凑，坚固和低成本单位。因此，由于其理想的脉冲和梁特性和可用输出功率，对使用掺杂型纤维激光器替代固态激光器的兴趣越来越大。此外，使用纤维增益培养基可以在没有特殊性要求的情况下进行室温运行，从而减少功耗。最近，人们对基于气体填充的空心光子晶体纤维（HC-PCF）的超脑（SC）产生的深度紫外线来源也引起了人们的兴趣。这样的方法提供了简化实施和包装的优势。该项目基于麦吉尔大学和O/E Land Inc.之间的现有合作，并集中于开发超紧凑，低成本和高功率深紫外线，具有高稳定性，高效率，高效率，效率和光束质量。将探索两个主要的研发推力：（1）优化光学系统构成非线性频率转换的效率，以及（2）通过GAS-FILLEDHC-PCFS生成深紫外线。成功的项目结果将使O/E土地能够开发新的激光器和来源，以解决土地技术差距，使其产品组合多样化，并为他们带来满足其客户需求的竞争优势。培训将为HQP提供发展技术知识并提高解决复杂问题并进行关键分析的机会；在Broad Photonics行业和雇主（包括MPBCommunications（Montreal，QC），QPS Photronics（Montreal，QC）和OZ Optics（Oz Optics（Ottawa））等雇主（包括光学组件和仪器供应商）中，高度寻求的技能。
