Applications of Resonator Mirrors CO₂ lasers, also known as gas lasers, are used for various applications, including:

Surface Processing:
This includes, for example, the marking of workpieces. Thanks to resonator mirrors, laser power can be precisely adapted to the requirements of each material. Organic materials require different settings than plastics or metals. CO₂ lasers can be used to mark materials such as leather, wood, and cardboard.

The use of CO₂ lasers for plastics is widespread. It is possible to gently remove coatings without compromising the structural integrity of components. This method also includes fiber-reinforced plastics.

Cutting:
Robust concave mirrors are crucial for the performance of CO₂ lasers. High output powers of gas lasers can be achieved without issue, enabling the cutting of various materials with the laser. Fast processing and clean cut edges are among the major advantages of this cutting method.

Welding:
CO₂ lasers are among the most powerful laser technologies available. With our resonator mirrors, strong joints can be created between two components for a wide variety of materials. The strength at the weld seam corresponds to the base strength of the materials used. This ensures stable joints without fractures or weak points.

Germanium Rear Mirror

Germanium is a versatile infrared material commonly used in the spectral range from 2 to 12 micrometers. It serves as a substrate for lenses, windows, and output couplers in low-power continuous-wave as well as pulsed TEA and CO₂ lasers. Ge optics with the lowest absorption are limited to a power range of 50 to 100 watts before thermal lensing or thermal runaway occurs. These issues can be minimized through proper heat dissipation of the optical material and careful cleaning of contaminated optical surfaces.

Germanium is non-hygroscopic, non-toxic, and offers good thermal conductivity, excellent surface hardness, and solid mechanical strength.

An ideal laser application for Ge is a >99% reflective rear mirror for a CO₂ laser. One side features a highly reflective, low-absorption dielectric coating, while the other side has an anti-reflective coating.
