Development of Novel, Compact Light Sources for Advanced Spectroscopy in Atmospheric Science and Materials Research

该项目开发新的激光仪器，并由大气科学和材料科学研究作为主要研究仪器计划的一部分联合支持。 研究人员正在与工业合作伙伴合作设计和构建一套多功能纳秒脉冲长度光学参量振荡器（OPO）。 所有参与者都在应用和建造最先进的光源方面拥有丰富的经验。 这些仪器将在大学研究人员小组中共享，用于大气自由基和温室活性气体的现场研究、临界大气反应的实验室研究、化学气相沉积的光学和红外诊断以及极端条件下固体地球矿物的特性分析。 通过开发新的激光系统，这些研究人员将加强现有的NSF赞助的研究，并探索和开发新的跨学科活动。 新的激光仪器将通过工业合作伙伴的参与，将提议者最近的几项发明转让给私营部门（即，Coherent、Spectra Physics和Casix，Inc.）。 对现有设计和从这种伙伴关系中产生的新开发仪器的许可，有助于将新的激光技术迅速转移到基础更广泛的科学和工程领域。 最后，该项目将使研究生和本科生参与几个OPO仪器开发子任务，并进一步涉及大气科学，团簇化学，薄膜沉积和固体地球材料的新应用的学生。 ATM-9724500

This project develops new laser instrumentation, and is supported jointly by Atmospheric Sciences and Materials Science Research as part of the Major Research Instrumentation Program. Researchers are designing and building a multi-functional suite of nanosecond pulse-length optical parametric oscillators (OPOs) in collaboration with industrial partners. All participants have extensive experience in the application and construction of state-of-the-art light sources. The instruments will be shared among the group of university researchers for in situ studies of atmospheric radicals and greenhouse active gases, laboratory studies of critical atmospheric reactions, optical and infrared diagnostics of chemical vapor deposition, and characterization of solid earth minerals under extreme conditions. By developing the new laser systems, these investigators will enhance existing NSF-sponsored research, and explore and develop new interdisciplinary activities. The new laser instrumentation will transfer several of the proposers' recent inventions to the private sector through the participation of the industrial partners (i.e., Coherent, Spectra Physics, and Casix, Inc.). Licensing of both existing designs and newly developed instruments emerging from this partnership assists the rapid transfer of new laser technology to broader-based science and engineering. Finally, the project will enable graduate and undergraduate participation in several OPO instrument development subtasks, and further involve the students in novel applications to atmospheric science, cluster chemistry, thin film deposition, and solid earth materials.
