    01 / Material

    Material Characteristics

    The base material of the reflective mirror is silicon, copper, Mo. The silicon is the normal coating material and it has the advantage of low cost, strong durability and stable thermal properties. The copper is usually used in the high power CO2 laser owing to its high thermal conductivity. The Mo can be used in a poor condition owing to its high surface strength and it can bear high power without surface coating, with long life span.

    02 / Physics

    Principle

    The reflective mirror is usually used as the end mirror or the folding reflective mirror in the laser cavity during the light transmission, while it's be acted as the role of the beam turn-back mirror outside the laser cavity. A CO2 laser mirror is a key optical component used in CO2 laser systems, which typically operate at a wavelength of 10.6 microns in the infrared spectrum. These mirrors are designed to reflect the high-power infrared laser beam with minimal loss and distortion.

    03 / Application

    Use

    CO2 laser mirrors are essential components in various industrial and scientific applications. They are primarily used in CO2 laser systems for tasks such as laser cutting, engraving, and marking, especially in materials like wood, plastics, metal, and glass. These mirrors help direct and focus the laser beam accurately, ensuring high precision and efficiency in the laser processes. CO2 laser mirrors are also used in research and development, including spectroscopy and medical applications like laser surgery, where precise beam delivery is critical. Their ability to handle high-power infrared laser beams while maintaining minimal distortion makes them indispensable in fields requiring advanced laser technology.

    Frequently Asked Questions

    What are the primary base materials for CO2 laser reflecting mirrors?
    The primary base materials are Silicon (Si), Copper (Cu), and Molybdenum (Mo). Silicon is popular for its low cost, durability, and stable thermal properties. Copper is preferred for high-power systems due to its high thermal conductivity. Molybdenum is ideal for harsh conditions due to its high surface strength and ability to withstand high power without a surface coating.
    What is the operating wavelength of these CO2 laser mirrors?
    CO2 laser mirrors are specifically designed to reflect high-power infrared laser beams with minimal loss and distortion, typically operating at a wavelength of 10.6 microns in the infrared spectrum.
    Where are CO2 laser reflecting mirrors typically used?
    They are widely used in industrial laser systems for cutting, engraving, and marking materials such as wood, plastics, metal, and glass. Additionally, they are used in scientific research (like spectroscopy) and medical applications including precision laser surgery.
    How does a mirror function inside vs. outside the laser cavity?
    Inside the laser cavity, the mirror serves as an end mirror or folding reflective mirror for light transmission. Outside the cavity, it acts as a beam turn-back mirror to direct and focus the laser beam accurately onto the target material.
    What is the difference between Chinese and Imported ZnSe materials?
    Imported ZnSe materials generally offer higher power handling capabilities and lower absorption rates, making them suitable for high-end industrial applications. Chinese ZnSe materials provide a cost-effective solution for standard power requirements while maintaining reliable performance.
    How do I choose the correct mirror diameter and focal length?
    Selection depends on your laser system specifications. Common diameters include 19.05mm, 20mm, 25.4mm, and 38.1mm. Focal lengths range from 38.1mm (1.5") to 190.5mm (7.5"). Refer to our specifications table or match your system's original optical model requirements.
