This Small Business Technology Transfer Phase I project aims to apply novel micro-discharge structures and techniques for exciting micro-lasers. The proposer will target wavelength regions not accessed by other compact lasers, emphasizing output wavelengths in spectral regions where diode pumped solid state laser approaches are considerably more complex than the proposed technology. The Phase I objectives include the development of the alignment and construction methods needed to make a stack of micro-discharges appropriate for laser action. The proposer will show laser action in the touchstone systems of the Mid-IR Xenon atom laser and the KrF laser in the ultraviolet. An analytical effort using state of the art, multi-dimensional discharge models will support experiments and guide the Phase II prototype design. The proposer will also define the needed risk reduction tests to produce a useful sensor system in Phase II. These very compact sources will be used in sensors for trace species detection, process control, and medical and food industry applications. The small size and low voltage operation will lead to inexpensive hand held uses and very compact automated industrial systems. The semi-conductor based fabrication techniques are inexpensive and systems based on this technology can significantly enhance the market potential. Specific commercial applications include: trace gas sensors for short ranges, screening solid surfaces and foods for pathogens, process controls, and fiber coupled probes for medicine.

这个小型企业技术转移一期项目旨在应用新的微放电结构和技术来激发微激光器。提议者将瞄准其他紧凑型激光器无法进入的波长区域，强调光谱区域的输出波长，其中二极管泵浦固体激光方法比提议的技术要复杂得多。第一阶段的目标包括开发校准和施工方法，以使一堆适合激光作用的微放电。本文将展示中红外氙原子激光器和紫外KrF激光器的试金石系统中的激光作用。使用最先进的多维放电模型的分析工作将支持实验并指导第二阶段的原型设计。提议者还将确定在第II阶段生产有用的传感器系统所需的降低风险测试。这些非常紧凑的源将用于传感器痕量物种检测，过程控制，以及医疗和食品工业的应用。小尺寸和低电压操作将导致廉价的手持使用和非常紧凑的自动化工业系统。基于半导体的制造技术价格低廉，基于该技术的系统可以显著提高市场潜力。具体的商业应用包括：短距离痕量气体传感器，筛选固体表面和食品的病原体，过程控制，以及用于医学的纤维偶联探针。
