Compact efficient lasers for bio-instrumentation illumination and online environmental monitoring

该项目的目标是开发用于生物仪器照明和在线环境监测的紧凑高效二极管泵浦固体（DPSS）激光器。所研制的生物仪器照明激光器将发射波长为561 nm（黄色）的光，输出功率为~5 W，而所研制的在线环境监测激光器将发射波长为中红外（mid-IR） （~3400 nm）的光。通过增加输出光的强度，只需要所需的波长，黄色激光器将用于生物仪器的照明。中红外激光器将用于检测甲烷气体，甲烷是最有害的温室气体（GHG）之一，对气候变化起着重要作用。这些激光器的发展将使加拿大公司在加拿大和全球市场上具有竞争优势，使他们不仅可以改进现有产品，还可以创造目前不存在的产品。黄色激光器的发展将导致生物照明技术的立即改进，这将直接影响加拿大人，提供更好的医疗设备，从而提高医疗质量。在线环境监测激光器的发展将使温室气体排放的广泛检测成为可能，这将有助于保护环境，并帮助加拿大成为其希望成为的气候行动的领导者。预计加拿大公司将从拟议激光器的成功开发中受益匪浅。

The goal of this project is to develop compact efficient diode pumped solid state (DPSS) lasers for bio-instrument illumination and online environmental monitoring. The developed bio-instrument illumination lasers will emit light at a wavelength of 561 nm (yellow colour) and have ~5 W output power, while the developed online environmental monitoring lasers will emit light with wavelengths at mid-infrared (mid-IR) (~3400 nm). The yellow laser will be used for illumination in bio-instrument by increasing the intensity of the output light with only desired wavelength. The mid-IR laser will be used for detection of methane gas, one of the most harmful green house gases (GHG) that contribute significantly to climate change. Development of these lasers will give Canadian companies a competitive edge in the Canadian and worldwide market by allowing them to not only improve their existing products but create ones that currently do not exist.The development of yellow lasers will lead to an immediate improvement in bio-illumination technology which will directly impact Canadians by providing improved medical equipment and thus higher-quality healthcare. The development of online environmental monitoring lasers will enable wide detection of GHG emission, which will help to preserve the environment and help Canada become a leader in climate action that it wants to be. It is expected that Canadian companies will benefit significantly from the success development of the proposed lasers.
