Proton fast-ignition: decouples the compression beam from a picosecond ignitor beam to achieve higher target gain at lower absolute driver energy — the most physics-efficient route to commercial ICF gain.
Requires target gain Q > 100 to overcome poor driver wall-plug efficiency — vs Q > 15 for MCF. NIF demonstrated Q ≈ 4.13 (April 2025), still mathematically distant from grid-connected ICF. The pivot toward p-¹¹B exploits Target Normal Sheath Acceleration (TNSA) to bypass bulk thermal heating via non-thermal avalanche reactions.
- Driver wall-plug efficiency: NIF-class flashlamp lasers sit at < 1%; diode-pumped solid-state and GaN blue diodes target 10–20%.
- Target manufacturing throughput: every shot consumes one precision-machined target — economics demand mass production at ¢-class unit cost.
- p-¹¹B Coulomb barrier requires T ≳ 150–200 keV and triple products of 10²⁴–10²⁵ keV·s·m⁻³.
- Rep-rate scaling: NIF fires once per ~6 hours; commercial plants need 10 Hz sustained for years.
- Driver capex dominates — diode-pumped solid-state and GaN blue-diode roadmaps target order-of-magnitude wall-plug efficiency gains.
- Target consumable cost per shot scales linearly with energy delivered — manufacturing automation is existential.
- Aneutronic p-¹¹B pivot eliminates the neutron-handling and tritium-breeding capex of D-T ICF.
Commercial ICF is pivoting rapidly to aneutronic p-¹¹B (Marvel, Blue Laser, HB11, Anubal). First Light's position is uniquely commercial — rather than build the driver, they manufacture the target 'amplifiers,' positioning as the indispensable 'fuel cartridge' provider to the broader industry. EX-Fusion leverages Japan's commercial optics manufacturing base; Focused Energy's split compression/ignitor beam architecture targets higher gain at lower driver energy.

Who built Focused Energy
Operating as a transatlantic bridge between German scientific precision and American venture capital scaling, Focused Energy was established to commercialize inertial confinement fusion. The technical vision is driven by Dr. Markus Roth, a globally recognized pioneer in laser-matter interactions and high-intensity particle beams. Complemented by the commercial execution of serial green-tech entrepreneur Thomas Forner and operations specialist Anika Stein, the team is deploying a "fast ignition" technique. By separating the initial fuel compression from the final ignition spark via ultra-fast lasers, they have created a highly reliable and efficient path to commercial laser fusion.
