2015 REU students

2017 REU Opportunity

Now accepting applications from undergraduate students interested in spending the summer of 2017 at the Extreme Light Laboratory. The research will involve the use of DIOCLES, an ultra-high-intensity laser system, and learning about the field of ultrafast science. 

Specific projects will be determined by matching student interest and experience with current laboratory experiments. A previous student described the summer as "very positive and educational,"  and another said, "it was a great learning experience throughout [the summer] working with a class IV laser.

To apply for the REU position, you will need to follow the steps as indicted on the REU website. The atomic, molecular, and optical physics REU program is sponsored by the National Science Foundation and the Nebraska EPSCoR program.

Lucas Heppner: Summer Research Program

Lucas Heppner was part of the 2016 Summer Research Program, where he worked on the project "A study of sensitive, large area detection systems for keV to MeV energy X-rays."

Study shines new light on electrons

It is not easy to follow an electron beam, travelling at the speed of light, while being ultra-small, ultra-short, and ultra-dense. As explained in Scientific Reports, ELL physicists used an ultra-intense laser pulse as a virtual electron detector. UNL Today compares the problem and solution to innovations used to capture images in photography.

Novel X-ray method using Diocles could detect nuclear materials

Physicists at the Diocles Extreme Light Laboratory at the University of Nebraska-Lincoln have demonstrated that their unconventional laser-based X-ray machine could provide a new defense against nuclear terrorism. Read the full story here.

Contemporary Physics Publication

One of four articles (originally published online during 2015) to be selected for the annual (2016) print cover of Contemporary Physics. This overview published in Contemporary Physics discusses the development of a new generation of accelerator-based hard X-ray sources driven exclusively by laser light.

RFP for laser light

The Extreme Light Core Facility (ELCF) is a core research facility at the University of Nebraska-Lincoln (UNL) designed to provide cutting-edge technology to NU researchers from a range of disciplines including engineering, physics, medicine, etc.
ELCF announces a new program to provide access to the novel capabilities of ultra-short pulses of high-peak power laser light. The opportunity to initiate preliminary experiments and collect foundational data can serve as the basis for future research proposals for federal funding. Learn more about the program and find application details in the RFP.

UNL Research Report available

The Extreme Light Laboratory was featured as the cover story in the 2013-2014 UNL Research Report, which is available on the web. The website features all the stories and art featured in the print version plus selected videos, additional photos and links to other information.

The 2013-2014 Research Report is also available in PDF format.

Latest ELL Publication

Optics Letters published an article reporting on the ELL group's successful efforts in continuing to develop an all-optical Compton x-ray source. This recent advance used all-laser-driven Compton scattering with second harmonic light to generate 9 MeV gamma-rays. First author Dr. Cheng Liu explains that this result is important because it is the first time, based on published results, an all-laser-driven system generated energy sufficient to be relevant to nuclear research and applications. Read the article for full details on this novel approach. View the full list of ELL publications for results published previously that led to this recent development.

Diocles laser

New Publication Featured

We are pleased to announce a new publication in Nature Photonics! The article reports on our research team developing a new way to generate synchrotron x-rays using the Diocles laser. The UNL announcement offers background and insight into the project, and explains the significance of generating high-quality x-rays from a compact source.
