LIBS (Laser-induced breakdown spectroscopy) is a technique which can identify the composition of a**substance by ablating a minute quantity, using a short pulsed laser and recording the emission spectrum**produced as ions in the plasma recombine. Sciencetech has a long background in manufacturing precision**spectroscopic equipment and through this engage grant will partner with Dr Sanderson to develop and test a**compact LIBS instrument capable of rapid setup utilizing high repetition rate, moderately powered nanosecond**laser sources available in the laboratory in Waterloo. The aim will be to prototype a design which is a relatively**economical and flexible product suited to today's market.**The new design will utilize moderate powered kHz, compact nanosecond laser in waterloo, and compare**results with a more conventional power laser system also available. To enhance the LIBS signal, plasma**characteristics will be modified using pressurized and evacuated environments. Furthermore the high**repetition rate of the laser source will be utilized by scanning the target. Parabolic light collection will be**utilized in conjunction with fibre coupled spectrometers, to maximize signal collection and minimize costs.**In addition to potential direct economic benefit to Sciencetech through sales of the newly designed LIBS**instrument, success of this project will lead to a new commercial LIBS molecular imaging instrument which is**attractive for a number of research and industrial applications. This can enhance Canadian competitiveness in**several industrial areas, health agriculture and manufacturing alone would constitute a multi-billion dollar**segment of the Canadian economy.

LIBS（激光诱导击穿光谱）是一种技术，它可以通过使用短脉冲激光烧蚀微量物质并记录等离子体中离子重组时产生的发射光谱来识别物质的成分。Sciencetech在制造精密光谱设备方面有着悠久的背景，通过此次参与资助，将与Sanderson博士合作开发和测试一种紧凑的LIBS仪器，该仪器能够在滑铁卢实验室中利用高重复率、中等功率的纳秒激光源进行快速设置。目标将是原型设计，这是一个相对**经济和灵活的产品适合今天的市场。**新设计将利用中等功率千赫，紧凑的纳秒激光器在滑铁卢，并比较**结果与更传统的功率激光系统也可用。为了增强LIBS信号，等离子体特性将在加压和真空环境下进行修改。此外，将利用激光源的高重复频率对目标进行扫描。抛物线光收集将与光纤耦合光谱仪结合使用，以最大限度地收集信号并最大限度地降低成本。**除了通过销售新设计的LIBS**仪器给Sciencetech带来潜在的直接经济效益外，该项目的成功将导致一种新的商用LIBS分子成像仪器，这对许多研究和工业应用具有吸引力。这可以增强加拿大在几个工业领域的竞争力，仅卫生农业和制造业就将构成加拿大经济中价值数十亿美元的部分。
