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.

Frequently Asked Questions
What base materials are typically used for CO2 laser reflecting mirrors?
CO2 laser reflecting mirrors are primarily made from silicon (Si), copper (Cu), or molybdenum (Mo). Silicon offers low cost and stable thermal properties; copper provides high thermal conductivity for high-power systems; and molybdenum features high surface strength for harsh conditions without needing a surface coating.
What is the working principle of a CO2 laser mirror?
These mirrors function inside the laser cavity as end mirrors or folding mirrors to facilitate light transmission. Outside the cavity, they serve as beam turn-back mirrors to accurately reflect and direct the high-power infrared laser beam (operating at 10.6 microns) with minimal loss and distortion.
What applications are CO2 laser mirrors used for?
They are widely applied in industrial processes such as laser cutting, engraving, and marking on materials like wood, plastics, metal, and glass. They are also vital in scientific research, spectroscopy, and medical fields for precision laser surgeries.
Why is copper preferred for high-power CO2 laser systems?
Copper is selected for high-power CO2 laser configurations due to its exceptional thermal conductivity. This property allows the mirror to efficiently dissipate heat, preventing thermal distortion and damage under high laser energy levels.
What makes molybdenum (Mo) mirrors suitable for harsh environments?
Molybdenum mirrors possess exceptionally high surface strength, allowing them to endure extreme working conditions and high laser powers without the need for delicate surface coatings, ensuring a remarkably long operational lifespan.
