The world’s first X-ray laser is not only a true laser, but it’s an extremely good one, according to measurements reported Sept. 30 in Physical Review Letters. Researchers studying the Linac Coherent Light Source (LCLS) characterized the coherence of the laser – the degree to which the light waves are synchronized – and found that it produces the most coherent X-ray radiation ever measured. With such a high-quality beam, the machine can determine atomic-scale structure of materials at a high level of precision, which will be useful in fields as diverse as drug discovery, materials engineering, and archaeology.”

Experiments show that the world’s first X-ray laser, the Linac Coherent Light Source, produces the most coherent (laser-like) X-rays ever measured.
