ACHIEVEMENT OF ESSENTIALLY FULL SPATIAL COHERENCE IN A HIGH-AVERAGE-POWER SOFT X-RAY LASTER

Journal Article · · Physical Review A

We report an observation of essentially full spatial coherence in a high average power soft-x-ray laser. Rapid coherence buildup due to strong refractive antiguiding in a long plasma column is experimentally demonstrated. This allows the generation of fully coherent, milliwatt-level average power soft-x-ray radiation by a tabletop device. The peak brightness of this laser reaches 2 x 1025 photons s-1 mm-2 mrad-2 within 0.01% spectral bandwidth, making it one of the brightest soft-x-ray sources available.
