CO2 lasers, also known as gas lasers, are used across all industries for the following work steps, among others:

Surface processing: This includes, for example, the marking of workpieces. Thanks to the cavity mirrors, the laser power can be adjusted exactly to the requirements of the respective materials. For organic materials, other values must be considered than for plastics or metals. CO2 lasers can mark leather, wood and cardboard, for example. 

The use of CO2 lasers for plastics is widespread. It is possible to gently remove paint without affecting the statics of components. This process also includes fibre plastics.

Cutting: The use of robust cavity mirrors is crucial for the performance of CO2 lasers. High output powers of the gas lasers can easily be achieved. This allows materials to be cut by laser. Fast processing and clean cutting edges are among the major advantages of these cutting methods. 

Welding: CO2 lasers are among the most powerful laser technologies. Thanks to our cavity mirrors, material bonds between two components can be ensured for a variety of materials. The strength at the weld seam is equal to the basic strength of the components used. This means that stable material connections are achieved without breakage or weak points.

Choose from the following CO2 laser mirrors to find the right products for your specific application:

• Copper mirrors
• Silicon mirrors
• Cavity mirrors
• Aluminium mirrors

We implement all relevant shapes of mirrors for laser applications according to your specifications:

• Plan
• Spherical (concave, convex)
• Toric
• Cylindrical 

Our development department is always interested in breaking new ground in laser technology together with you. We are pioneers in the field of cavity mirrors for CO2 lasers. Our mirrors are perfectly adapted to the special, harsh conditions inside CO2 laser cavities. The result is high stability of the laser mode and laser power. This benefits your company in industrial manufacturing processes.

Typically, the operational wavelength of CO2 lasers is 10.6 µm. The CO2 molecules within the laser tube radiate in this frequency range as their states of activity change.

As reflectors within the laser, the CO2 laser mirrors intensify this frequency range of 10.6 µm and ensure a constant laser output. Depending on the geometric nature, our CO2 laser mirrors and lenses also improve the focal range of the laser beam.

Copper mirrors are the perfect choice when highest laser powers are to be achieved. These CO2 laser mirrors can be used for demanding applications from laser cutting to laser welding because copper has a very high thermal conductivity, and it is also possible to integrate cooling lines directly into the CO2 laser mirrors.

Molybdenum coated copper mirrors are used for laser welding. Due to the hardness of molybdenum, the mirror coating can be cleaned without scratching it. 

Molybdenum absorbs CO2 laser radiation at a higher rate than other coatings for this laser. Since a layer of molybdenum only a few micrometres thick is applied to copper substrates in these mirrors, the good thermal conductivity of the copper is retained and the CO2 laser mirrors can be passively or actively cooled without any problems.

Cavity mirrors are high-power mirrors for CO2 laser cavities. The cavity mirrors are designed and manufactured in excellent quality, so that these CO2 laser mirrors achieve the highest standards in terms of reflection and stability. 

Advanced manufacturing techniques ensure the preservation of laser power, laser mode, and consistent stability under the demanding conditions found in CO2 laser cavities. In addition, the external optics are ideally designed for operation in industrial environments.

Do you need high-quality CO2 laser mirrors? You can choose between laser mirrors with metallic and dielectric coatings, providing the right reflection for any application. The powerful optical mirrors are made of copper or silicon. Copper mirrors are available in plano, spherical, parabolic, toroidal or cylindrical. 

The CO2 laser mirrors made of silicon can be ordered in plano, spherical or cylindrical versions. Of course, our development department also works out ready-to-use components according to your specifications.

Our CO2 laser mirrors are also available for medical applications: In medical technology, CO2 lasers are used for gentle surgical procedures such as the treatment of scarred tissue.
