High-Quality CO2 Laser Reflecting Mirrors from China Suppliers and Factory for Engraving and Cutting Applications
Product Details
Material characteristics
01The 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
02The 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
03CO2 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
Q: What base materials are used for CO2 laser reflecting mirrors?
The primary base materials used are Silicon (Si), Copper (Cu), and Molybdenum (Mo). Each material is selected based on the specific power requirements and environmental conditions of the CO2 laser system.
Q: How do I choose between Silicon, Copper, and Mo mirrors?
Silicon is ideal for standard systems due to its low cost, durability, and stable thermal properties. Copper is preferred for high-power CO2 lasers because of its superior thermal conductivity. Molybdenum (Mo) is best for harsh operational environments because of its high surface strength, allowing it to withstand high power without requiring surface coatings.
Q: What is the primary function of a CO2 laser reflecting mirror?
It serves as either an end mirror or a folding reflective mirror inside the laser cavity to facilitate light transmission, or as a beam turn-back mirror outside the cavity to direct and focus the laser beam onto target materials.
Q: At what wavelength do CO2 laser mirrors typically operate?
These mirrors are specifically designed to reflect high-power infrared laser beams operating at a wavelength of 10.6 microns in the infrared spectrum with minimal energy loss and distortion.
Q: What industrial applications require CO2 laser mirrors?
They are critical components in industrial applications such as laser cutting, engraving, and marking for materials like wood, plastics, metal, and glass. They are also used in spectroscopy research and medical procedures like laser surgery.
Q: What is the difference between Chinese and Imported ZnSe materials listed in the table?
Imported ZnSe (Zinc Selenide) typically offers lower absorption rates and higher purity, making it suitable for higher power thresholds and precision optical performance, whereas Chinese ZnSe provides a cost-effective solution for standard laser applications.
