Physics<\/a> doctoral candidate John Beetar spends his day studying how electrons interact on an extremely short timescale, called attoseconds.<\/p>\n

At this scale, electron dynamics are still not very well understood, especially in solid materials. That\u2019s one reason Beetar is driven to conduct his work. He wants to contribute to the understanding of this highly evolving field, which could someday lead to faster wireless communications and quantum computers.<\/p>\n

Beetar\u2019s research uses a new kind of laser beam to shoot pulses of light into different materials. Using these pulses as an attosecond strobe light, he takes \u201csnapshots\u201d to figure out what the electrons are doing at a particular instant in time.<\/p>\n

One of the main challenges in this type of research is to create the laser pulses, which are like tiny \u201cbullets\u201d of light. Beetar is introducing new ways to create the required pulses using simpler, more reliable laser technologies. Whereas current technology requires large, complex laser facilities and highly trained operators, Beetar\u2019s technique can be applied using lasers which are more commonly used in industrial applications such as glass cutting.<\/p>\n

\u00a0\u201cWe are now developing new technology that will allow us to perform measurements that can\u2019t currently be done anywhere else.\u201d \u2014 John Beetar, UCF doctoral candidate<\/p><\/blockquote>\n

UCF has earned a reputation for excellent work within the ultrafast community, which is one reason Beetar selected the university for his doctoral work. These experts include Mike Chini, assistant professor of physics and Beetar\u2019s lab director.<\/p>\n

\u201cUCF is very well positioned to take a leading role in the ultrafast community. We are now developing new technology that will allow us to perform measurements that can\u2019t currently be done anywhere else,\u201d Beetar says. \u201cThere are still hurdles that we need to overcome, but if we are able to make this technology work then we can contribute to the scientific community in a big way.\u201d<\/p>\n

Beetar will be presenting his research at UCF\u2019s Student Research Week<\/a>, March 30-April 3.<\/p>\n","protected":false},"excerpt":{"rendered":"
