CREOL Fall Colloquium Series: Dr. Xiaoming Yu - Explore novel laser-induced phenomena for materials processing

Wednesday, August 17, 2022 11 a.m. to noon

Abstract: The interaction between ultrashort laser pulses and solid materials has unique characteristics that can be explored to enhance the capabilities of laser-based materials processing and precision manufacturing. In this talk, I will discuss recent results in my group regarding laser-matter interaction at intensities close to and beyond the laser damage threshold, and the development of novel methods for materials processing at the micro and nano-scale. I will discuss the generation of surface structures with size below the diffraction limit by manipulating photoionization pathways, “volumetric microfabrication” with three-dimensionally structured light fields, and the development of laser processing systems for industrial applications. These results address current issues of resolution and throughput that have long been the bottleneck for adopting ultrafast lasers in manufacturing applications, and open the door to new materials processing modalities enabled by a better understanding of photophysical and photochemical processes under extreme conditions.


About the Speaker: Dr. Xiaoming Yu is an assistant professor at CREOL, College of Optics and Photonics, at the University of Central Florida. He received BS in Physics from Nankai University, China, in 2008, MS in Plasma Physics from Shanghai Institute of Optics and Fine Mechanics in 2012, and PhD in Industrial and Manufacturing Systems Engineering from Kansas State University in 2016. He established the Ultrafast Laser Processing group at CREOL in 2017. His research interest is in laser-matter interaction and laser-based advanced manufacturing. He is an NSF CAREER Award recipient, and has published more than 40 journal articles in the field of ultrafast laser materials processing. He has given invited talks at conferences such as FiO, Photonics West, and Optical Sensors. His work on volumetric microfabrication received the Best Student Paper Award at Photonics West 2022.
