This Small Business Innovation Research Phase II project is to develop a shortwavelength, narrow-bandwidth, high-brightness photo-ionization laser; that can be used for used for ultra-high energy-resolution, angle-resolved photoemission spectroscopy (ARPES), and for single-photon-ionization (SPI) in order to improve mass spectroscopy-based detection capabilities of complex organic molecules, especially low-vapor-pressure explosive compounds and trace residues. The compact size, efficient optical conversion, and high brightness of the proposed laser source will enable integration into "field-ready", on-line mass spectrometry tools. The capabilities of the proposed single-photon-ionization light source will also complement a broad array of established mass-spectral analysis techniques to enable the development of instruments capable of analyzing heterogeneous samples with no a-priori knowledge of the sample composition. This capability is urgently needed for a variety of homeland security and non-proliferation applications.

本小企业创新研究二期项目是研制一种短波长、窄带宽、高亮度的光电离激光器;其可用于超高能量分辨率、角分辨光电子能谱（ARPES）和单光子电离（SPI），以提高复杂有机分子的基于质谱的检测能力，特别是低蒸汽压爆炸性化合物和痕量残留物。紧凑的尺寸，高效的光学转换，和高亮度的激光源将能够集成到“现场准备”，在线质谱工具。拟议的单光子电离光源的能力也将补充广泛的一系列既定的质谱分析技术，使仪器的发展能够分析不均匀的样品，没有先验知识的样品组成。这种能力是各种国土安全和不扩散应用所迫切需要的。
