Overview of Molybdenum reflection CO2 laser mirror
Molybdenum (Mo) is a chemical element with the atomic number 42 and is represented by the symbol Mo on the periodic table. It is a transition metal located in group 6 and period 5. Molybdenum is known for its high melting point, excellent strength, and thermal stability, making it a crucial component in various industrial applications.
Feature of Molybdenum reflection CO2 laser mirror
-
High Melting Point: Molybdenum has one of the highest melting points among all pure elements, at 2,623°C (4,753°F). This property makes it ideal for high-temperature applications.
-
Strength and Toughness: Even at high temperatures, molybdenum maintains its strength and hardness, which is essential for use in extreme environments.
-
Corrosion Resistance: Molybdenum exhibits good corrosion resistance to many acids and alkalis, although it can be attacked by oxidizing acids like nitric acid.
-
Thermal Conductivity: It is an excellent conductor of heat, making it suitable for applications where efficient heat transfer is required.
-
Alloying Agent: Molybdenum is widely used as an alloying agent, particularly with steel, to enhance hardness, toughness, and resistance to wear and corrosion. Stainless steels often contain molybdenum for these properties.
-
Electrical Applications: Due to its low resistivity and high-temperature stability, molybdenum is used in electrical contacts and heating elements.
-
Lubricity: Molybdenum disulfide (MoS₂) is a common dry lubricant, providing low friction surfaces in high-pressure, high-temperature conditions.

Parameters of Molybdenum reflection CO2 laser mirror
Molybdenum (Mo) is a popular material for high-quality mirrors used in CO2 laser systems due to its excellent reflectivity, thermal stability, and resistance to laser-induced damage. The specific parameters for a molybdenum reflection CO2 laser mirror may vary depending on the manufacturer and the intended application, but some key characteristics include:
1. Reflectivity: Molybdenum has a high reflectivity for CO2 laser wavelengths, typically around 99% or more. This ensures that a significant portion of the laser energy is reflected back into the cavity.
2. Absorption coefficient: The lower the absorption coefficient, the better the mirror’s performance. Molybdenum has a low absorption rate for CO2 laser light, which reduces heat generation and helps maintain the mirror’s surface integrity.
3. Surface finish: A smooth and polished surface is crucial for laser mirrors. The surface roughness (Ra) is usually specified in nanometers (nm), with values below 50nm for optimal performance.
4. Thermal expansion coefficient: Molybdenum has a relatively low coefficient of thermal expansion compared to other materials, which helps minimize distortions due to temperature changes during operation.
5. Laser-induced damage threshold (LIDT): This is the maximum energy density a mirror can withstand without permanent damage. For CO2 lasers, the LIDT for molybdenum is generally higher than many other materials.
6. Durability: Molybdenum mirrors are known for their long service life, as they can withstand high-intensity laser exposure without degrading quickly.
7. Coating: Often, a protective or anti-reflection coating is applied to the molybdenum substrate to enhance performance, reduce ghosting (secondary reflections), and improve durability.
When selecting a molybdenum CO2 laser mirror, it’s essential to consider the specific requirements of your application, such as power level, wavelength, and operating environment, to ensure the best-suited product with the appropriate specifications. Always consult the manufacturer’s data sheets or technical specifications for detailed information.

FAQ
-
What are the primary uses of Molybdenum reflection CO2 laser mirror?
Molybdenum reflection CO2 laser mirror is primarily used in the production of steel alloys, accounting for over 80% of its consumption. It’s also used in chemicals, lubricants, electronics, and specialized applications like lighting and nuclear energy.
-
Is molybdenum found naturally?
Yes, molybdenum is found naturally in the Earth’s crust, often in minerals like molybdenite (MoS₂) and powellite (CaMoO₄). It is mined as a byproduct of copper mining.
-
How does Molybdenum reflection CO2 laser mirror affect human health?
In small amounts, molybdenum is an essential trace element for humans, playing a role in enzyme functions. However, excessive intake can lead to toxicity, though this is rare under normal dietary conditions.
-
Is molybdenum magnetic?
Molybdenum itself is not magnetic. It is classified as a diamagnetic material, meaning it repels magnetic fields slightly rather than being attracted to them.
-
