Laser line (narrow-band) mirrors

HR | 193 nm - 7000 nm

3photon laser line (narrowband) mirrors can be designed for specific laser types or custom wavelengths depending on your device or application.
Dense ion beam sputtering (IBS) coating, less expensive electron beam evaporation (EBE) or ion assisted deposition (IAD) can be used to apply dielectric mirror coatings. Various optimizations of angle of incidence can be done by 3photon coating engineers.

 

  • Substrates
  • Standard Mirrors

Material

Substrates of 3photon standard mirrors are made of UVFS (usually Corning 7980) material. This material has perfect properties to allow 3photon engineers to polish it smoothly to 10-5 Scratch-Dig. Also, good transmitted and reflected wave-front distortion (flatness (Peak-Valley)) values can be reached <λ/10 @ 632.8 nm.

For non-standard applications we can also polish and provide other materials such as N-BK7, germanium, calcium fluoride and others.

Shape and curvature (ROC)

Standard 3photon laser line mirrors are round either Ø25.4 mm or Ø12.7 mm in diameter and 6 mm or 3 mm thickness. However, complex figures like cylindrical convex or concave, aspherical are what we do every day. 3photon engineers are experienced to work with various sizes from micro-optics <2 mm to large optics of >400 mm in diameter.

Angle of incidence

Laser line mirror (narrow band mirror) coating can also be designed to work on different angles if necessary. 3photon standard laser line mirror is designed to perform at normal incidence angle (0°), however experienced 3photon engineers are ready to design output couplers to work in other angles, like 22.5°, 45°, 56° or broad angle diapason 0-22°; 0-45°.

Reflection

Depending on laser medium and cavity structure the reflection values may vary. 3photon can offer:

  • Standard reflection of >99.8 % at 0° angle of incidence, using electron beam evaporation (EBE) or ion assisted deposition (IAD) technologies.
  • High reflection >99.99.. % employing ion beam sputtering (IBS) technology.
