Commercially available nonlinear optical crystals are used in a number of defence and civilian applications to access mid-infrared wavelengths that would otherwise not be available from standard laser systems. In this project the student will learn to fabricate novel nonlinear materials needed to access the far-infrared spectrum where chemical fingerprinting can be performed. The student will also learn to design and build laser systems for upconversion detection, a technique used to convert invisible radiation to visible, detectable wavelengths and enable imaging in difficult conditions.

商业上可获得的非线性光学晶体用于许多国防和民用应用中，以获得标准激光系统无法获得的中红外波长。在这个项目中，学生将学习制造新的非线性材料需要访问远红外光谱，其中化学指纹可以执行。学生还将学习设计和构建用于上转换检测的激光系统，这是一种用于将不可见辐射转换为可见，可检测波长并在困难条件下成像的技术。
