Physicist Pushes Boundaries of Photonics and Electronics

​Much of what Dr. Xiaoqin "Elaine" Li researches is completely invisible to the human eye. She works with materials that are merely a few atoms thick and observes processes that occur within a trillionth of a second.

Keck Foundation Awards $1.5 Million for New Method to Cool Atoms and for Student Research

Graduate student Erik Anciaux works on the “Ultra-Bright Atom Laser” project in the Raizen lab.

The W. M. Keck Foundation has awarded scientists at The University of Texas at Austin two grants totaling $1.5 million to develop a powerful, alternative method for cooling atoms and involve more undergraduate students in using new advanced technologies for research.

Backstage Pass to the Texas Pettawatt Laser

Backstage Pass to the Texas Pettawatt Laser

Science writer and UT Austin alumnus Joe Hanson (Ph.D. '13) takes us on a tour of the Texas Center for High Intensity Laser Science, home of the Texas Pettawatt Laser. Photos by Robert Schults evoke the awe and mystery of this fundamental research. Read the article in the July/August 2014 edition of the Alcalde: 1,000,000,000,000,000 Wat...

Trapping a Bacterium in a Laser Beam Aids Study of Biofilms

Scientists at The University of Texas at Austin have developed a technique to move and position a single bacterium using a highly focused laser. The precise control offered by this tool will allow researchers to better study how bacterial biofilms form.

The Ultimate in High Speed Cinematography Reveals Laser Gymnastics at Speed of Light

Scientists in the Department of Physics have captured the ultimate high-speed movie of a laser pulse as it zips through a piece of glass at the speed of light. The new imaging technique will help scientists understand how intense laser pulses propagate through air, glass fibers and fusion pellets, and thus could have applications in atmospheric chemical analysis, fiber optic communications, and power generation.
