Yes, infrared lasers can cut certain types and thicknesses of metal.
Infrared (IR) lasers are commonly used in laser cutting applications for a variety of materials, including some metals. The effectiveness of an IR laser in cutting metal depends on several factors:
-
Laser Power and Wavelength: Higher power lasers are generally required for cutting thicker metals. The specific wavelength of the infrared laser can also affect its absorption rate by the metal.
-
Metal Type: Some metals are more easily cut with infrared lasers than others. Aluminum, stainless steel, and copper are examples of metals that can be cut with IR lasers, provided the appropriate laser parameters are used.
-
Metal Thickness: Infrared lasers can typically cut thin sheets of metal more effectively. For example, it's possible to cut aluminum up to 0.05 inches thick with an IR laser. Cutting thicker metals requires higher laser power and slower cutting speeds.
-
Laser Cutting System: The specific laser cutting system used (e.g., fiber laser, CO2 laser) influences the cutting capabilities. Fiber lasers, which operate in the infrared spectrum, are often preferred for metal cutting due to their high beam quality and efficiency.
In summary, while infrared lasers can cut metal, the success depends on the type and thickness of the metal, as well as the power and type of the laser being used. Fiber lasers in the infrared range are commonly employed for this purpose, especially for cutting thin sheets of aluminum, stainless steel, and copper.
