Optical Power Limiters Countering Frequency Agile Lasers and Dazzlers
SBIR Opportunity Analysis
The U.S. Navy, through DOD SBIR topic DON26BZ01-NV012, is seeking Mid-Wave Infrared/Long-Wave Infrared nonlinear optical dyes embedded in sol-gel glass to create optical power limiters that protect electro-optical sensors from frequency-agile lasers and dazzlers. The work calls for developing a passive, self-activating protection concept and then demonstrating prototype optical-limiting elements that can be integrated with mid-infrared transparent windows and embedded vision or periscope systems. Key priorities include high transmission in normal conditions, rapid response and recovery, strong attenuation under laser illumination, broad acceptance angles, manufacturability, and reliable domestic dye synthesis and availability, with Phase II work potentially classified and subject to U.S.-ownership and security-clearance requirements. Phase I is centered on feasibility, material preparation, and limited laboratory testing, while Phase II covers prototype fabrication and testing, and applications are due June 3, 2026 at 4:00 PM UTC.
