Lasers have the unique capability to deliver highly collimated light across a wide range of wavelengths (colours). Laser imaging does not currently extend to the mid-infra red region, which although beyond the detection range of the eye can be useful in a similar way that night-vision is of practical assistance today. Furthermore, when the light from an object is analysed, the specific colours enable identification of different molecules by their absorption signatures . Conventional glass fibers are opaque at these wavelengths, but new glasses and fiber designs have recently become available with improved infra-red transmission properties. The proposed research will use this technology to create wavelength tunable laser sources. As the complexity and cost of current lasers severely restricts the number of users the proposed research will use glass fibers to develop more practical laser sources for the future. Glass is a good laser material since it is an inexpensive solid, and by using a fiber light-pipe geometry to maintain alignment complex mirror arrangements can be avoided. To create such sources research is needed in a study of the characteristics of both the lasers and the fiber geometries to obtain an optimum combination. Laser development requires new materials, theoretical modelling, and experimental work. The novel materials currently emerging from the host University's laboratories would be used to develop fiber laser sources that may become the preferred choice for future scientific and industrial laser users.

激光具有独特的能力，可以在广泛的波长（颜色）范围内提供高度准直的光。激光成像目前还没有扩展到中红外区域，虽然超出了眼睛的探测范围，但它的用处与今天夜视的实际帮助类似。此外，当分析来自物体的光时，特定的颜色可以通过它们的吸收特征来识别不同的分子。传统的玻璃纤维在这些波长下是不透明的，但是最近有新的玻璃和纤维设计可以改善红外传输性能。提出的研究将使用该技术来创建波长可调的激光源。由于目前激光器的复杂性和成本严重限制了用户的数量，因此提出的研究将使用玻璃纤维来开发未来更实用的激光源。玻璃是一种很好的激光材料，因为它是一种廉价的固体，并且通过使用光纤光管的几何形状来保持对准，可以避免复杂的反射镜安排。为了创建这样的光源，需要对激光器和光纤几何形状的特性进行研究，以获得最佳组合。激光的发展需要新的材料、理论建模和实验工作。目前来自主办大学实验室的新材料将用于开发光纤激光源，这可能成为未来科学和工业激光用户的首选。
