This proposal falls under the Manufacturing with light call and addresses the area of Pulsed Laser Deposition (PLD) as a route to manufacturing high optical quality, fully single crystal lasing waveguides. PLD is an established technique for deposition of a range of materials, but few so far have used it to grow single crystal structures for application as thin-film lasers. This project is directed at this specific area, and has end goals of high power (>100W c.w.) lasing operation, from compact (< 1square cm) devices at laser wavelengths in the 1.0 - 2.0 micron region, as well as q-switched and mode-locked pulsed laser operation. The second goal is to demonstrate the utility of these devices for applications across the range of laser-based manufacturing, including materials processing, and the life-sciences and medical areas in particular. We will engage with laser companies, the UK association of laser users and laser job shops to establish the optimum market for such devices and then work with all of these to seek a route to commercialisation of these products. Given the short duration of the project, we will direct our effort to ensure the optimum device outcome (c.w. or pulsed operation) following the initial growth and characterisation phase, for maximum impact within the manufacturing sector.

这项建议属于光制造技术，涉及脉冲激光沉积(PLD)领域，作为制造高光学质量、全单晶激光波导的一种途径。PLD是一种用于沉积一系列材料的成熟技术，但到目前为止，很少有人使用它来生长单晶结构，作为薄膜激光的应用。该项目针对这一特定领域，最终目标是高功率(&gt；100W C.W.)小型(1平方厘米)器件的激光工作波长在1.0-2.0微米范围内，以及调Q和锁模脉冲激光工作。第二个目标是展示这些设备在各种基于激光的制造中的应用，包括材料加工，特别是生命科学和医疗领域。我们将与激光公司、英国激光用户协会和激光工作商店合作，为这类设备建立最佳市场，然后与所有这些公司合作，寻求这些产品的商业化途径。鉴于项目持续时间较短，我们将尽最大努力确保最佳设备结果(C.W.或脉冲操作)在初始增长和特征阶段之后，以便在制造部门内产生最大影响。
