Which laser is most widely used for laser cutting and Why ?

The laser most widely used for laser cutting applications, especially in industrial settings, is the CO2 laser. This type of laser operates at a wavelength of around 10.6 micrometers, which is highly absorbed by materials such as metals, wood, plastics, and organic materials. CO2 lasers are favored for cutting because they can deliver high-power beams efficiently and are capable of cutting through a wide range of thicknesses and materials with high precision. They are particularly suitable for industrial materials processing due to their versatility, reliability, and cost-effectiveness for a variety of cutting applications.

In industrial laser cutting, the CO2 laser is the most commonly used due to its ability to cut a broad range of materials effectively. Its wavelength allows it to be absorbed well by materials like metals and non-metals alike, making it versatile for various manufacturing and fabrication tasks. CO2 lasers are preferred for their capability to deliver continuous high-power output, ensuring efficient and precise cutting across different material types and thicknesses.

The suitability of a laser for cutting depends on the specific requirements of the application. While CO2 lasers are widely used for their versatility and efficiency in cutting a wide range of materials, other types of lasers such as fiber lasers and Nd

lasers also have specific advantages. Fiber lasers, for instance, are excellent for cutting metals due to their high beam quality and energy efficiency, making them suitable for thin to medium thicknesses of metal sheets. Ndlasers are known for their durability and are used in specialized cutting applications, particularly for thicker materials or where precise control over the heat-affected zone is crucial.


Laser cutting utilizes different types of lasers depending on the material and the desired cutting characteristics. CO2 lasers are preferred for cutting non-metallic materials like wood, plastics, fabrics, and composites, thanks to their wavelength and power output that is well-matched to the absorption properties of these materials. Fiber lasers are increasingly used for cutting metals due to their high energy efficiency and ability to deliver high power in a compact design, making them suitable for high-speed cutting of thin to medium thickness metal sheets. Nd

lasers, while less common in industrial cutting compared to CO2 and fiber lasers, are utilized for specific applications requiring high precision and reliability, particularly in sectors such as aerospace and medical device manufacturing.


In industrial materials processing applications, the CO2 laser remains the most widely used type for laser cutting. Its ability to cut a wide range of materials efficiently and accurately, coupled with its relatively lower operating costs compared to other types of lasers, makes it a preferred choice for manufacturers across various industries. CO2 lasers are integral to modern manufacturing processes, offering versatility and reliability that meet the demands of industrial-scale cutting operations effectively.
