Partial support is requested for the purchase of a visualization system, consisting of (1) a copper vapor laser flash combined with a high speed ICCD camera, and (ii) an infrared imaging system. The equipment will greatly improve the PI's ability to study the basic mechanisms governing the interaction between high powered laser beams and solid materials that are being processed (cutting, drilling, shaping, welding, joining). A research program studying the cutting and shaping of ceramics is under current NSF support, but the program suffers from lack of diagnostic equipment. The requested high speed camera will permit detection and quantification of debris in the plume, measurement of regression of surface and re-deposition of debris, the onset and propagation of cracks and formation and collapse of the keyhole. The infrared system will permit the determination of temperature maps. Together, the equipment will constitute a powerful tool for the study of laser-material interaction processes.

要求提供部分支助， 可视化系统，包括（1）铜蒸气激光器 闪光灯结合高速ICCD相机，和（ii） 红外成像系统设备将大大改善 PI的能力，研究的基本机制， 强激光与固体相互作用 正在处理的材料（切割，钻孔， 成形、焊接、连接）。一项研究计划， 陶瓷的切割和成形在当前NSF的支持下， 但该项目缺乏诊断设备。的 要求的高速摄像机将允许检测， 对羽流中的碎片进行量化， 表面退化和碎片再沉积， 裂缝的形成和扩展， 钥匙孔红外系统将允许确定 温度图这些设备将共同构成 研究激光与物质相互作用的有力工具 流程.
