Marvel Fusion, a Munich-based laser fusion company using nanostructured targets and ultra-short-pulse lasers, is building a $150 million multi-petawatt laser research facility with Colorado State University, targeted for completion in 2026. It has also co-designed a conceptual fusion power plant with Siemens Energy.

Notes
first plasma target holds the facility completion target (2026), which may slip. private funding raised (EUR 385m) mixes private equity and public cooperation funding. Marvel's preferred fuel is p-B11 (aneutronic) per company materials; not re-verified here. developer type public-private reflects CSU partnership.
