Low Loss HR Mirrors

Low Loss HR mirrors are essential in laser systems where the lowest possible losses are required. Mirrors are manufactured with Ion Beam Sputtering technology (IBS) reaching extremely high-quality specifications. IBS thin films feature higher density and durability than e-beam coatings, making them resistant to environmental conditions such as heat, humidity and pressure. IBS mirrors reach highest reflectance (>99.9%) in a certain wavelength range and angles of incidence (AOI). Also, scattering is minimized which is usually a limiting factor for high reflectivity.

Features

  • Resistant to environmental conditions
  • Wide-angle (AOI: 0-50°) mirrors are available
  • Mass production capabilities: 1000 pieces per month
  • Reflectance higher than 99.9%
  • Surface flatness, P-V: <λ/8 @ 632.8nm
  • Laser damage threshold up to 17J/cm² @ 1064nm, 10ns, 10Hz

Phase Retardation Reflectors : Silicon for CO2 Lasers and 10.6µm

These mirrors create a 90° Phase Shift with the aid of specially constructed thin film coating layers applied to the surface, when hit with a linear polarized beam at 45° to the plane of incidence. Commonly called Phase Shifters, Polarizers, or Circular Polarizing Mirrors, they transform the incoming beam into a circular polarized state. They typically are only used external to the laser cavity as a beam delivery mirror. These operate only with a true 10.6µm laser wavelength and will not work at other wavelengths such as 9.2 or 9.6µm without special modifications to the thin film coating design. We offer non-standard wavelength Phase Retardation Reflectors at these other wavelengths as custom parts.

  • Phase Shift: 90°±3.0° between p and s polarization for 10.6µm operation only @ 45° Angle Of Incidence
  • Reflectance: > 99.0% average @ 10.6µm
