Optics publication

New Article Published

The Extreme Light group has a new article published in Optics Letters! As discussed in the article, the efforts of our research team led to greater spectral phase control by means of an adaptive feedback closed-loop. This phase control capability enabled the experimental study of the dependence of laser wakefield acceleration on the spectral phase of intense laser light.

World's Brightest Laser at Extreme Light Laboratory featured in Lab Manager Magazine

From article in Lab Manager Magazine

"While scientists in fiction often use lasers for evil, researchers in the real world use them to help humankind. The University of Nebraska-Lincoln’s Extreme Light Laboratory (ELL) is home to one particularly unique laser that could benefit us in many ways...."

Bright light leads to Nature Photonics publication

Congratulations to post-doctoral fellow and first-author, Wenchao Yan, and the ELL research team on their recent publication featured on the cover of the August 2017 issue of the journal Nature Photonics.  The research explores high-order multiphoton Thomson scattering, where hundreds of discrete photons are simultaneously scattered from individual electrons. Evidence for the highly nonlinear electron motion is seen from the spatial profiles of the x-ray beams, which became elongated along the direction of laser polarization as the strength of the light fields increased and the electron’s figure-8 orbit became more pronounced. To achieve the requisite light intensity, an ultra-powerful laser was focused to 10^20 times higher than that of sunlight on Earth.
