Fiber raman lasers and nonlinear frequency generation

光纤激光器已成为增长最快的激光器类型在过去几年中，由于其独特的特点 **，如耐用性，减少持续维护，功率效率和低成本。它们在通信、仪器、传感和医疗手术等众多领域都有重要的应用; 2017年，全球光纤激光器的总收入预计将达到14.1亿美元。虽然光纤激光器市场最初专注于1550 nm波长范围，但光纤激光器在紫外线，可见光，** 和中红外波长范围内的机会越来越多。这样的波长可以使用全光纤拉曼激光器和非线性 ** 频率产生来获得。这项研究代表了麦吉尔大学和O/E**Land Inc.之间的战略合作。其针对的关键挑战是开发1650 nm的低成本、高功率、可广泛调谐的拉曼光纤激光器以及它们的非线性频率转换以获得800 - 850 nm以及400 - 425 nm的辐射。在1650 nm的光纤激光器是非常重要的化学传感，激光雷达，和自由空间 ** 通信，但不容易从传统的掺杂光纤;在800 - 850 nm和400**- 425 nm的源用于生物光子学，光子量子信息，时间分辨光谱学，和 ** 荧光显微镜，等等。成功的项目结果将使O/E Land能够开发这些新的激光产品，填补商业上的空白，增加他们的技术组合，并在满足客户需求方面给予他们竞争优势。HQP的培训将为他们提供解决复杂问题，进行批判性分析和发展特定技术技能的机会，这些技能对加拿大信息和通信技术（ICT）部门的广泛雇主（包括光学元件和仪器供应商，如MPB Communications）非常有价值。（Montreal，QC）、EXFO（魁北克市，QC）、OZ Optics（渥太华，ON）和Lumentum（渥太华，ON）。

Fiber lasers have become the fastest-growing laser type for the last few years due to their distinctive features**such as durability, reduced on-going maintenance, power efficiency, and low cost. They have important**applications in numerous fields from communications, instrumentation, sensing, and medical surgery; in 2017,**the total fiber laser revenue worldwide is projected to be $1.41 billion. While the fiber laser market initially**focused on the 1550 nm wavelength range, there are increasing opportunities for fiber lasers in the UV, visible,**and mid-IR wavelength ranges. Such wavelengths can be obtained using all-fiber Raman lasers and nonlinear**frequency generation. This research represents a strategic collaboration between McGill University and O/E**Land Inc. that is directed at the key challenge of developing low-cost, high-power, widely tunable Raman fiber**lasers at 1650 nm as well as their nonlinear frequency conversion to obtain radiation at 800 - 850 nm as well as**400 - 425 nm. Fiber lasers at 1650 nm are of great importance chemical sensing, LIDAR, and free-space**communications, yet are not readily available from conventional doped-fiber; sources at 800 - 850 nm and 400**- 425 nm are used in biophotonics, photonic quantum information, time-resolved spectroscopy, and**fluorescence microscopy, amongst others. A successful project outcome will allow O/E Land to develop these**new laser products and address a gap in what is commercially available, add to their technology portfolio, and**give them a competitive advantage in meeting their clients' needs. Training of HQP will provide them with**opportunities to solve complex problems, perform critical analysis, and develop specific technical skills that**are highly valuable to the broad Canadian Information and Communications Technologies (ICT) sector**employers including optical component and instrumentation suppliers such as MPB Communications**(Montreal, QC), EXFO (Quebec City, QC), OZ Optics (Ottawa, ON), and Lumentum (Ottawa, ON).
