中文摘要
激光诱导加工是离子束的优秀替代品,具有独特的优点,包括通过直接写入或光学投影进行图案化,而不需要接触掩模,更高的刻蚀速率,以及增强的表面完整性。这个项目研究用电子束或激光束取代离子束。本研究项目将通过(1)在各种液体介质中进行纳秒(Ns)-激光化学气相沉积(CVD)-金刚石抛光和钻孔实验,以及(2)通过激光的实验诊断和理论建模:液体介质中的钻石相互作用,来加深对激光辅助和液体诱导反应加工技术的基本理解。
英文摘要
Laser-induced machining is an excellent alternative to ion beams with distinct benefits including patterning by direct writing or optical projection without contact masks, higher etch rates, and enhanced surface integrity. This project investigates a substitution of ion beam with an electron beam or a laser beam. This research project will develop a fundamental understanding of laser-assisted and liquid-induced reactive machining technique by (1) performing nanosecond (ns)-laser chemical vapor-deposited(CVD)-diamond polishing and drilling experiments in various liquid media, and (2) by experimental diagnosis and theoretical modeling of laser : diamond interaction in liquid media.
