Laser for widefield quantum diamond microscope

The National Institute of Standards and Technology, under the Department of Commerce, seeks procurement of one diode-pumped solid-state laser operating at 532 ± 3 nm wavelength for widefield quantum diamond microscopy, with proposals due August 25.

Place of performance is Gaithersburg, Maryland. The laser must deliver a minimum output power of 5 W with continuous tunability from 50 mW to 5 W and meet rigorous optical specifications: spectral purity greater than 99%, full-width half-maximum linewidth less than 30 GHz, beam quality (M²) less than 1.1, beam divergence less than 0.5 mrad, beam circularity of 1.0 ± 0.1, linear polarization ratio greater than 100:1, power stability of ±1% or lower, and noise less than 0.1% rms. Additional requirements include warm-up time of 10 minutes or less, beam pointing stability less than 5 µrad/°C, beam position stability less than 5 µm/°C, a stand-alone chiller if liquid-based cooling is employed, a shutter mechanism, and PC-based software for remote operation. The system must be new equipment only; used, remanufactured, experimental, prototype, custom, and gray-market components are explicitly prohibited.

Delivery is FOB Destination to NIST within 90 days after receipt of order. The Government will conduct visual inspection and performance testing within 30 business days of receipt to verify wavelength and power output. Payment is 100% upon installation and acceptance by the technical point of contact following successful testing, with Net 30-day terms. The contractor must provide minimum one-year warranty coverage in accordance with FAR 52.212-4. The NAICS code is 334516, Analytical Laboratory Instrument Manufacturing; PSC is 6640, Laboratory Equipment and Supplies.
