MRI: Acquisition of Ultrafast Laser Processing and Diagnostic System

这一重大研究仪器(MRI)奖将支持收购超快(飞秒)激光处理和诊断系统，用于材料加工和诊断领域的研究、研究培训和教育。该设备将使以下领域的研究和教育成为可能：(1)金属、合金、陶瓷、聚合物、复合材料和电子材料的超快激光微加工；(2)各种材料薄膜的超快激光沉积；以及(3)超高速成像和诊断技术及其应用的开发。设备设施将为设在各个工程和科学系以及新成立的老自治领大学应用研究中心的不同教职员工和研究生共享资源。这将在各种材料和加工技术方面的专家教员与更擅长光学和激光以及新的工业互动的教员之间发展新的互动。材料的激光加工被认为是21世纪的制造技术，是世界范围内加强和扩大当前“最先进技术”的努力的一部分。目前的激光加工是通过热加工进行的，能量效率不高。超快激光技术为各种材料的微加工和薄膜涂层等材料加工提供了一种非热方法。基于支持的超快激光设备的研究推进将对当前激光物质相互作用、成像、光谱学和各种制造技术的知识进步产生重大影响。

This Major Research Instrumentation MRI) award will support the acquisition of an ultrafast (Femtosecond) laser processing and diagnostic system for research, research training and education in the area of materials processing and diagnostics. This equipment will enable research and education in the areas of: (1) ultrafast laser micromachining of metals, alloys, ceramics, polymers, composites and electronic materials; (2) ultrafast laser deposition of thin films of various materials; and (3) development of ultrafast imaging and diagnostics techniques and their applications. The equipment facility will be a shared resource for various faculty members and graduate students located in various engineering and science departments and the newly formed Applied Research Center of the Old Dominion University. This will develop new interactions between faculty members who are experts in various materials and processing technology with the faculty whose expertise is more towards optics and lasers as well as new industrial interactions. Laser processing of materials is considered a manufacturing technology for the 21st century, and part of the worldwide effort to enhance and expand the current "state of the art". Current laser processing occurs by thermal processes and is not very energy efficient. Ultrafast laser technology provides a non-thermal method for materials processing such as micromachining and coating of films of various types of materials. The research thrusts based on the supported ultrafast laser facility will have significant impact on the current advancement of the knowledge on laser matter interaction, imaging, spectroscopy and on various manufacturing technologies.
