**Identifier:** DAF27BZ01-DV010
**NAICS:** 541715

The U.S. Air Force is seeking a rugged, kilowatt-class 2-micron fiber amplifier prototype through an SBIR research and development topic.
- **Government buyer:** Department of War, Department of the Air Force (USAF), through Air Force Materiel Command (AFMC) and the Small Business Innovation Research (SBIR) Program.
- **Request:** Direct-to-Phase-II research and development for a low-size, weight, and power (SWaP) 2-micron fiber amplifier for directed-energy applications.
- **Prototype:** One fully functional, rugged amplifier prototype capable of output above 1 kW, beam quality M² below 1.2, linewidth below 5 GHz, spectral stability, and electro-optical efficiency above 25%. No part number is specified.
- **Deliverables and validation:** Prototype hardware, complete electrical and optical schematics, and a test and characterization report validating the required performance.
- **Transition objective:** Phase III aims to move the technology toward production and integration into a deployable multi-kilowatt laser defense system.
- **Notable requirements:** The opportunity is for eligible small businesses and requires CMMC Level 2 (Self). No specific OEMs, vendors, commercial product models, or purchase quantities are named beyond the single prototype requirement.
