Three Main Types of Lasers for Cutting
Laser cutting is a process that uses a laser to cut materials, which is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Laser cutting works by directing the output of a high-power laser, by computer, at the material to be cut.
In order to make sure that the laser-cutting process is successful, it is important to choose the right type of laser for the job. There are three main types of lasers used for cutting: CO2 lasers, Nd: YAG lasers, and fiber lasers.
CO2 Lasers
CO2 lasers are the most common type of laser used for cutting. They are available in a wide range of sizes and power levels, making them suitable for a variety of different applications. CO2 lasers are ideal for cutting materials such as wood, acrylic, plastics, paper, and other non-metallic materials.
Nd: YAG Lasers
Nd: YAG (neodymium-doped yttrium aluminum garnet) lasers are a type of solid-state laser that is more powerful than CO2 lasers and is able to cut thicker materials, including metals. Nd: YAG lasers are commonly used in the automotive and aerospace industries.
Fiber Lasers
Fiber lasers are the newest type of laser used for cutting. They are a type of solid-state laser that uses a glass fiber as the gain medium. Fiber lasers are the most powerful type of laser available and can cut thicker materials than either CO2 or Nd: YAG lasers. They are also much more efficient and require less maintenance than other types of lasers.
When choosing a laser for cutting, it is important to consider the type of material that will be cut, the thickness of the material, and the power of the laser that is needed. Each type of laser has its own advantages and disadvantages, so it is important to choose the right type for the job.
