The National Institute of Standards and Technology (NIST) is seeking information from potential sources capable of providing an Optical Parametric Oscillator (OPO) as part of its research on atomic layer deposition under the CHIPS Act. The OPO must meet specific technical requirements, including continuous wave operation, a tuning range from 2.3 to 4.0 µm, and a minimum output power of 1 W, among other specifications, to facilitate mid-infrared spectroscopy for analyzing process gases. Interested vendors are encouraged to respond with their capabilities and relevant information by contacting Jenna Bortner or Donald Collie via email, as the government intends to issue a Sole Source Award to Toptica Photonics if no other capable sources are identified. Responses should be submitted as soon as possible, preferably before the closing date, and must not include proprietary information.
