The National Institute of Standards and Technology (NIST) is conducting market research to identify potential sources for an ultraviolet 266-nm pulsed laser head compatible with its existing time-resolved photoluminescence system. The procurement aims to replace visible laser heads with a 266 nm pulsed laser for characterizing wide bandgap semiconductor materials such as GaN or SiC, requiring specific performance capabilities including picosecond pulses and an average power of at least 1 mW at a repetition frequency of 80 MHz. Interested vendors must submit detailed information about their products, including specifications, customization options, and service offerings, by emailing the primary contact, Cielo Ibarra, at cielo.ibarra@nist.gov. This sources sought notice is for market research purposes only and does not constitute a commitment to issue a solicitation or award a contract.
