> xLight is developing a particle-accelerator-powered free-electron laser to supply extreme-ultraviolet light to multiple semiconductor lithography scanners from outside the fab. Its first prototype is planned for Albany, New York, with a $150 million federal incentive award supporting construction and demonstration.

- **Founded:** 2021
- **Headquarters:** Palo Alto, United States
- **Founders:** Nicholas Kelez (Founder; CEO and CTO)
- **Products:** Free-electron laser EUV light source, Fab-scale EUV light delivery
- **Notable:** Closed a $40 million Series B in July 2025., Secured a finalized $150 million CHIPS incentive award in June 2026., Established public R&D collaborations with Fermilab, Los Alamos and Cornell CLASSE.

## Products & services

- **Free-electron laser EUV light source** — A proposed accelerator-based source located outside a fab and designed to distribute EUV light to multiple lithography scanners; first prototype planned at Albany Nanotech.
