Fit reasons
- NAICS alignment with historical contract wins in similar service areas.
- Scope strongly matches core technical capabilities and delivery model.
Risks
- Past performance thresholds may require one additional teaming partner.
- Potential clarification needed on staffing minimums before bid/no-bid.
Next steps
Validate eligibility requirements, assign capture owner, and schedule partner outreach to confirm teaming strategy before submission planning.
Quick Summary
The National Institute of Standards and Technology (NIST), specifically the Fundamental Thermodynamics Group, is conducting market research through a Sources Sought notice to identify potential sources for a Narrow-Linewidth, Frequency-Doubled 556 nm Laser System. This is not a request for quote, and no award will be made from this notice. The government is seeking domestic commercial products if available. Responses are due February 25, 2026.
Purpose & Background
NIST's Fundamental Thermodynamics Group requires this laser system for research related to cesium and ytterbium atomic gas measurements, supporting their work in thermodynamic measurements and primary thermometer development. This notice serves as a market research tool to gauge industry capabilities.
Key Requirements / Deliverables
NIST requires one (1) Narrow-Linewidth, Frequency-Doubled 556 nm Laser System with specific technical specifications:
- Narrow Seed Laser: Wavelength 1111.60 nm, output power >= 130 mW, polarization extinction ratio >= 20 dB, linewidth <= 1 kHz. Must include USB, TCP/IP, Python programmability, PC GUI, and PID controller with lock-in detection.
- Frequency-Doubled Fiber Amplifier: Output wavelength bandwidth 555.5 nm to 556.5 nm, frequency-doubled output power >= 1 W, linewidth <= 2 kHz, relative intensity noise < 0.1 % RMS (100 Hz - 10 MHz), power stability +/- 0.5 % over 8 h, polarization extinction ratio > 300:1. Control via rack-mountable electronics, USB, TCP/IP, PC GUI.
- Laser Narrowing Electronics: Must include Pound-Drever-Hall (PDH) error signal generation/detection (2 channels) and a PID controller with fast (>= 50 MHz bandwidth) and slow (>= 15 kHz bandwidth) feedback outputs. Control via USB or TCP/IP interfaces and PC GUI.
Submission & Response Instructions
Interested firms should submit documentation demonstrating their ability to meet the minimum requirements and technical specifications. This may include brochures, manuals, reports, or videos. Proprietary information should not be submitted. Required response elements include company name and address, point of contact (phone, email), teaming partners (if applicable), supply type (COTS, modified COTS, prototype), and any other pertinent information.
