This Small Business Innovation Research (SBIR) Phase I project has as its goal the demonstration of the feasibility of an optical alloy analysis instrument based on a microchip laser excitation source. This instrument will determine elemental composition using laser-induced plasma spectroscopy (LIPS). It will have the advantage over existing portable instruments of being able to determine concentrations of light elements such as carbon, aluminum and silicon. The key to this innovation is the microchip laser, which has been shown to have several advantages in LIPS applications, while being remarkably small, lightweight and robust. In Phase I observations will be made using a laboratory LIPS apparatus, and a set of specifications will be derived for an instrument capable of determining carbon in steel at levels of interest to potential customers in industries where alloy identification is critical. This proposal involves collaboration with a manufacturer with a dominant position in the market. With their input, the optimum instrument configuration which can offer both useful capabilities and easy, portable operation will be determined.There currently exists a strong market for alloy identification instruments, even though existing devices are either limited by inability to determine some of the most important elements, or by significant drawbacks in portability and ease of use. An optical device with important advantages could lead to a much expanded market.

该小型企业创新研究（SBIR）第一阶段项目的目标是演示基于微芯片激光激发源的光学合金分析仪器的可行性。 该仪器将使用激光诱导等离子体光谱法（LIPS）测定元素组成。 与现有的便携式仪器相比，它的优势在于能够确定碳、铝和硅等轻元素的浓度。这一创新的关键是微芯片激光器，它已被证明在LIPS应用中具有几个优势，同时非常小，重量轻，坚固耐用。在第一阶段，将使用实验室LIPS仪器进行观察，并将推导出一套能够确定钢中碳含量的仪器的规格，该仪器的含量应符合合金识别至关重要的行业中潜在客户的利益。这项建议涉及与在市场上占主导地位的制造商合作。 有了他们的输入，最佳的仪器配置，可以提供有用的功能和简单，便携式操作将被确定。目前存在着一个强大的市场，合金识别仪器，即使现有的设备要么是无法确定一些最重要的元素，或显着的缺点，在便携性和易用性。具有重要优势的光学设备可能会导致更大的市场。
