U.S.-Hungary Research on Ultrashort Laser Pulses

威廉·马什·赖斯大学的弗兰克·蒂特尔博士和捷特大学的扎索特·波尔博士共同开展的这项美国-匈牙利研究项目的主要目标是，是追求两个相关的主题：1)新的超短激光脉冲技术和2)利用直接激光烧蚀或光化学处理来制造纳米结构。这些努力旨在促进新型宽带超短激光脉冲放大器的发展，并促进我们对利用直接激光烧蚀制造纳米结构的理解。这个项目的结果将有助于我们了解紫外光激光烧蚀聚合物的基本物理机制，并将为我们深入了解新的光化学诱导吸收是否通过直接光解形成等重要问题提供帮助。化学反应或其他光化学过程后形成的自由基。结果可能导致对干涉仪的改进，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。这个有关量子电子学、波和束流的项目通过使美国和东欧的顶尖研究人员能够结合互补的人才，并在具有强烈共同兴趣和能力的领域汇集研究资源，实现了促进科学知识的计划目标。

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.
