Laser Mirrors & Laser Windows for High Power Laser Laser Mirrors and Laser Windows with High Damage Thresholds

Laser Mirrors and Laser Windows with High Damage Thresholds

Features

  • High damage threshold
  • High reflectivity (Laser Mirrors)
  • High transmittance (Laser Windows)
  • Customizable

Our Laser Mirrors and Laser Windows feature high damage thresholds to high output YAG and Ti-sapphire Lasers. To a YAG laser wavelength of 1064 nm (10 ns, 20 Hz, 1 on 1), the world's top-class laser induced damage threshold of 190 J/cm2 has been achieved for the Laser Mirrors, and 140 J/cm2 for the Laser Windows. The Laser Mirrors have a reflectance of 99.9 % or higher, and the Laser Windows have a transmittance of 99.6 % or higher, both offering high performance.
These products contribute to the development of a variety of fields, leading to improvements to quality and workability of laser finishing, the achievement of state-of-the-art medical treatments by laser equipment, analytical applications in the life sciences, and the development of new materials.

The product line includes 36 cost-efficient Laser Mirrors and 12 Laser Windows. They can be customized to suit your needs such as optical characteristics, external shape, and surface figure guaranteed after coating.
