This engineering research equipment grant is to acquire an Nd: YAG pulsed laser with a pulse energy of 50J to perform research in the area of manufacturing processes. The projects for which the Nd:YAG laser equipment will be used include: (1) advanced laser drilling methods for the production of noncircular holes; (2) synthesis of metallic classes by laser glazing; (3) innovative laser welding of recently developed Al-Li alloys; (4) laser machining of super alloys; and (5) development of superhard coatings by laser vapor deposition. The objectives of research with Nd:YAG laser equipment are threefold: (1) to address the basis issues in near infrared laser beam-material interactions during processing; (2) to examine the mechanisms responsible for the process advantages and methods to minimize manufacturing defects; and (3) to assess the superiority of laser processing over other nontraditional machining methods.

这项工程研究设备赠款是为了获得一台脉冲能量为50J的脉冲激光器，用于在制造工艺领域进行研究。将使用激光设备的项目包括：(1)用于生产非圆孔的先进激光打孔方法；(2)通过激光上光合成金属类别；(3)对最近开发的Al-Li合金进行创新的激光焊接；(4)高温合金的激光加工；以及(5)通过激光气相沉积开发超硬涂层。激光加工设备的研究目标有三个：(1)解决加工过程中近红外激光束与材料相互作用的基本问题；(2)研究导致工艺优势的机制和将制造缺陷降至最低的方法；以及(3)评估激光加工相对于其他非传统加工方法的优越性。
