The National Institute of Standards and Technology (NIST) is conducting market research to identify sources capable of supplying a high-performance 5 W, 532 nm diode-pumped solid-state laser for use in a widefield quantum diamond microscope. The laser must meet detailed minimum specifications including continuous tuning from 50 mW to 5 W, TEM00 spatial mode, beam quality M2 < 1.1, and power stability within ±1%. Interested parties are asked to submit company details, product specifications, customization capabilities, pricing, and other relevant information as outlined in the notice. This is a sources sought notice for planning purposes only and does not obligate the government to award a contract. No specific submission deadline, budget, or performance location is stated in the notice.
