About this file
This document is a Price Schedule (ITN-2025-054-JS) for Large Aperture Laser Optics issued by Colorado State University's Advanced Lasers and Extreme Photonics (ALEPH) Lab, seeking high-precision laser mirrors for the new ATLAS Laser Facility. The solicitation requires 12 half meter-scale laser mirrors across five line items: 5 HR800nm 45-degree mirrors, 2 HR800nm 30-degree mirrors, 3 HR400nm/HR800nm 45-degree mirrors, 5 HR400nm/AR800nm 27.5-degree dichroic mirrors, and 8 coating test samples. Delivery is specified for Item 5 within 4 months of order receipt, with Items 1-4 to be delivered by August 1, 2026.
The price schedule details extensive technical specifications for each mirror type, including precise dimensional requirements, material specifications (Corning 7980 2F), surface figure tolerances, reflectivity ranges, and coating requirements. Key technical parameters include surface flatness (< lambda/10 and lambda/4), high reflectivity (> 99.5-99.8%), low surface roughness (< 1.0 nm RMS), and a desired laser-induced damage threshold of >0.8 Joule/cm2. The mirrors are intended for use in vacuum environments and require comprehensive documentation, including full aperture interferograms, efficiency measurements, and inspection reports. Vendors must submit detailed specifications and literature for evaluation, with the university reserving the right to approve coating test samples before proceeding with the full order.
