U.S.-Hungary Research on Ultrashort Laser Pulses

这项由威廉·马什·赖斯大学的弗兰克·蒂特尔博士和塞格德JATE大学的佐尔特·波尔博士共同开展的美国-匈牙利研究项目的主要目标是研究两个相关课题：1)新型超短激光脉冲技术和2)利用直接激光烧蚀或光化学加工生产纳米结构。这些努力旨在促进新型宽带超短激光脉冲放大器的发展，并促进我们对使用直接激光烧蚀生产纳米结构的理解。该项目的结果将有助于我们了解聚合物的紫外激光烧蚀的基本物理机制，并对诸如新的光化学诱导吸收剂是否通过直接光解离形成，化学反应后自由基的形成，或者其他光化学过程。研究结果可能导致干涉仪的改进，该干涉仪能够通过直接激光蚀刻在有机材料中产生纳米结构。这个量子电子学、波和束的项目实现了推进科学知识的计划目标，使美国和东欧的领先研究人员能够在共同感兴趣和有能力的领域结合互补的人才和集中研究资源。

The primary objective of this U.S.-Hungary research project between Dr. Frank Tittel of Williiam Marsh Rice University and Dr. Zsolt Por of JATE University, Szeged, is to pursue two related topics: 1) novel ultrashort laser pulse techniques and 2) production of nanostructures using direct laser ablation or photochemical processing. These efforts are intended to contribute to development of new broadband ultrashort laser pulse amplifiers, and to advance our understanding of the production of nanostructures using direct laser ablation. Results of this project should contribute to our knowledge of basic physical mechanisms of UV laser ablation of polymers and should offer insight on such important questions as whether new photochemically induced absorbers are formed by direct photo dissociation, radical formation after a chemical reaction, or other photochemical processes. Results may lead to refinements for an interferometer capable of producing nanostructures in organic materials by direct laser etching. This project in quantum electronics, waves and beams fulfills the program objective of advancing scientific knowledge by enabling leading researchers in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of strong mutual interest and competence.
