Mid-IR SpecTRometry with QuAntum Dot Lasers (MISTRAL)

量子点是半导体材料的微小结构，比沙粒小100万倍，可以发光。它们的特性（发射波长）可以通过选择半导体成分和调整它们的尺寸来控制。量子点（QDot）在激光技术中的应用始于上世纪90年代。这是一个相对较新的领域，尽管世界上只有少数供应商存在，但它们具有非常有吸引力的商业气体传感特性。Cascade Technologies设计和制造基于先进激光技术的气体分析仪，适用于环境监测、气体加工工业、食品工业、制药等一系列市场。这些系统的商业限制之一是它们的制造价格（主要组成部分之一是激光器的价格），激光器性能和激光器发射波长的可用性。在这个项目中，Cascade技术公司和兰开斯特大学将合作设计、制造和测试与气体传感应用相关的QDot激光器。进入中红外区域的新波长意味着Cascade将进入不同的市场。的降价

Quantum dots are tiny structures of semiconductor materials 1 million times smaller than a sand grain that can emit light. Their properties (emission wavelength) can be controlled by the choice of semiconductor composition and by adjusting their size. The use of Quantum Dots (QDot) in lasers technology started in the 90s. This is a relatively new area and, although only a few suppliers worldwide exist, they have very attractive properties for commercial gas sensing. Cascade Technologies designs and manufactures gas analysers based on advanced laser technology for a range of markets: environmental monitoring, gas process industries, food industries, pharmaceuticals. One of the commercial limitations of these systems is their manufacturing price (one of the main components being the price of the laser), the laser performance and the laser’s emitting wavelength availability. In this project, Cascade Technologies and Lancaster University will work together to design, build and test QDot lasers relevant to gas sensing applications. The access to new wavelengths in the mid-IR region would mean that Cascade would gain access to different markets. A reduction in price of the
