Shanghai team in laser breakthrough

Shanghai team in laser breakthrough

Chinese scientists have used a novel approach to achieve free-electron lasing that may result in the production of low-cost, tabletop FEL devices, offering the possibility of breakthroughs in multiple disciplines.

 

It was the first time researchers had achieved FEL using a laser wakefield electron accelerator, a method for producing high-energy electron beams using an accelerating field structure. 

 

After nearly a decade's effort, a paper about the achievement by the Chinese Academy of Sciences' Shanghai Institute of Optics and Fine Mechanics was published as the cover story of the United Kingdom-based scientific journal Nature, on Thursday.

 

X-ray FEL can be used to detect the internal dynamic structure of matter and study the interaction of light with atoms, molecules, and condensed matter, which may lead to breakthroughs in disciplines as diverse as physics, chemistry, structural biology, medicine, new materials, energy, and the environment.

 

Experts said there are eight FEL facilities operating around the world but they range in size from 300 meters to 3.4 kilometers and use radio frequency electron accelerators not suited to the development of small FEL facilities that could be more widely used.

 

Researchers said small FEL facilities have great potential in producing images of rapidly moving objects. Even if a patient-an uncooperative child, for example-undergoing X-ray imaging was moving quickly, they said, a machine using the technology would still be able to produce impressive high-resolution images.
