RESEARCH BRIEFINGS 25 February 2026 Current X-ray lasers require facilities that are kilometres long. A cavity-based set-up about 66 metres in length has been developed that uses highly reflective mirrors to enable the generation of high-intensity pulses of narrow-band X-ray radiation. This promises to overcome the limitations of current X-ray lasers. This is a summary of: Rauer, P. et al. Lasing of a cavity-based X-ray source. Nature 650, 93–96 (2026).
