Pure (Undoped) YAG Windows

×
  • Excellent Mid-Wave IR (MWIR) (4 - 5µm) Transmission
  • Available in 5, 10, 12.5, and 25mm Diameters
  • Commonly Used in White Light Generation

Pure (Undoped) YAG Windows feature a durable pure Yttrium Aluminum Garnet (YAG) substrate that offers good transmission from 210 – 5500nm in the UV to MWIR spectra. Their high thermal conductivity and excellent optical properties make them suitable for use as protective windows in higher-energy laser systems. These windows produce broadband white light when pumped with an ultrafast laser, allowing for use in femtosecond white light (continuum) generation. Featuring excellent durability and high optical transparency, these windows facilitate precise laser delivery and measurement in medical and industrial laser systems. Pure (Undoped) YAG Windows, unlike sapphire, do not experience transmission dips in the MWIR, making them ideal for use with MWIR illumination sources and Quantum Cascade Laser (QCL) applications.
