Invitation to Negotiate ITN-2025-054-JS Large Aperture Laser Optics

Section I. Background, Overview, and Goals A. Background Colorado State University is one of the nation’s top public research universities and an institution on the rise. In the past decade, CSU has produced record enrollment, built on all-time highs in student diversity and student success; outpaced ambitious record fundraising goals; produced groundbreaking research driven by a highly productive faculty; offers a campus revitalized by a transformational building campaign; and, perhaps most important, provides an unrivaled learning environment. CSU currently offers 76 undergraduate degree programs and 118 graduate degree programs, and has made significant investments in student recruitment, financial aid, student services, and retention. CSU is also the “university of choice” for Colorado residents: More Colorado high-school students choose CSU than any other institution of higher education in the state. CSU prides itself on the notion of being a force of good for the world and challenges all its faculty, staff, and students to make their own imprint every day.

B. Overview The Colorado State University Advanced Lasers and Extreme Photonics (ALEPH) Lab is seeking firm pricing on large aperture laser mirrors as part of a facility upgrade project for the new ATLAS Laser Facility. CSU requires pricing and specifications for quantity 12 half meter-scale laser mirrors. These mirrors must have a very flat wavefront, high reflectivity over specified wavelength ranges, high laser damage threshold, low dispersion, and be suitable for use in vacuum, Detailed specifications for these mirrors are provided in Section II of the Invitation to Negotiate.

Section II. Specifications and Requirements A. Specifications The optics described in the specifications and requirements below are offered to vendors as to the quality, specifications and functionality CSU ATLAS Laser Facility requires. NOTE: The product you are quoting must meet or exceed specifications and requirements indicated below. Please provide full specifications and literature for the optics for which you are bidding. THE ESTIMATES OF PURCHASE AND USAGE INCLUDED IN THIS ITN ARE ESTIMATES ONLY. PURCHASES UNDER ANY AGREEMENT RESULTING FROM THIS ITN MAY BE MORE OR LESS THAN THE ESTIMATES PROVIDED IN THIS ITN. COLORADO STATE UNIVERSITY DOES NOT REPRESENT, WARRANT, OR GUARANTEE THAT THE UNIVERSITY WILL PROCURE ANY PARTICULAR DOLLAR VALUE OR ANY PARTICULAR QUANTITY UNDER ANY AGREEMENT RESULTING FROM THIS ITN.
