PID-Based Laser Frequency Stabilization System Development

The contract entails the design and implementation of a PID feedback control system to externally stabilize laser frequency with real-time calibration and long-term drift correction capabilities. The system must precisely regulate laser output frequency by leveraging proportional-integral-derivative control algorithms tuned for high stability and minimal error accumulation over extended operational periods. Real-time calibration mechanisms are required to continuously adjust for environmental and component-induced variations, while long-term drift correction features must autonomously compensate for thermal, mechanical, and electronic aging effects without manual intervention. The work is to be performed in Boulder, Colorado, under a subcontract arrangement with the National Institute of Standards and Technology, part of the U.S. Department of Commerce. The project falls under NAICS code 541715, indicating it involves scientific research and development services focused on physical, engineering, and related sciences. Proposals must be submitted by August 7, 2026, following a posting date of July 28, 2026. Success will depend on delivering a robust, field-deployable system capable of maintaining laser frequency stability under varying conditions, meeting stringent NIST performance benchmarks for precision metrology and calibration applications.
