Sole Source Purchase of Narrowband, Stable Laser Systems for Atomic Physics Experiments

The University of New Mexico is seeking to purchase narrowband, stable laser systems for atomic physics experiments. The lasers must be specified for atomic resonances in cesium atoms and must have certain properties such as narrow linewidths, good thermal stability, and a large mode-hop free tuning range. The proposed vendor is TOPTICA, and the purchase will be made through a sole source procurement. The university has searched for other sources but found that TOPTICA's lasers are the only ones that meet their specific needs. * The laser systems must be able to be configured at different wavelengths, specifically 850 nm and 894 nm. * The lasers must have a typical instantaneous linewidth of 5 kHz and a frequency stability of less than 100 MHz/K. * The lasers must have a mode-hop free tuning range of 30-50 GHz. * The university has contacted other vendors, including MOGLABS, Vescent, and Newport, but found that their lasers do not meet the required specifications.
