High-Quality 30mm CO2 Laser Reflecting Mirror from Reliable China Suppliers and Factory
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 it's high thermal conductivity. The Mo can be used in a poor condition owing to it's high surface strength and it can bear high power without surface coating, with long life span.
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.
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.

They are designed to operate in the infrared spectrum, typically at a wavelength of 10.6 microns, which is standard for CO2 laser systems.
What is the difference between cavity mirrors and turn-back mirrors?
Inside the laser cavity, the mirrors function as end mirrors or folding reflective mirrors. Outside the cavity, they serve as beam turn-back mirrors to guide and deliver the laser beam to the target area.
What are the main applications of CO2 laser mirrors?
They are heavily used in industrial laser cutting, engraving, and marking machines for materials like wood, plastics, metal, and glass. They are also used in spectroscopy, scientific research, and medical laser surgeries.
Why is Molybdenum (Mo) preferred for harsh working environments?
Molybdenum has an exceptionally high surface strength. It can handle high-power laser beams without needing surface coatings, allowing it to survive harsh conditions and provide a very long lifespan.
