The National Institute of Standards and Technology (NIST) is seeking to procure a Noventa single-mode 532 nm laser for use in Brillouin Light Scattering Spectrometers, with the intent to issue a Sole Source Award to Government Scientific Source if no alternative suppliers are identified. The laser must meet specific technical requirements, including an output power of 250 mW, suppression of higher order modes, and various dimensional and performance specifications to ensure compatibility with existing equipment. This procurement is critical for NIST's ongoing research into magnetic wavelike excitations, and interested parties are encouraged to respond with their capabilities and relevant product information by contacting Elizabeth Timberlake or Donald Collie via email. The notice serves as a market research tool and does not constitute a commitment to award a contract.
