Types of Lasers and How they Work

If you’ve been considering a sheet metal fiber laser cutting machine, you’ve probably wondered which kind of laser to buy. The following article will discuss the differences between fiber lasers, CO2 lasers, and laser/punch machines. Then, we’ll discuss how each of these types of lasers can perform cutting and other functions. Once you’ve decided on the type of laser you want, you can begin the process by selecting the best machine for your needs.

CO2 lasers:

There are many benefits of using a CO2 laser for sheet metal fiber laser cutting. It produces better edge quality on the metal workpiece, and its flexibility spans the spectrum of laser applications. Despite their age, CO2 lasers are highly reliable, with predictable operating costs. However, CO2 lasers have more expensive initial setup costs, such as mirrors, lenses, bellows, and las gasses. The CO2 resonator is the most expensive component, so CO2 lasers tend to be more expensive than fiber lasers.

Fiber lasers:

The high-powered fiber-optic beam is effective for piercing materials such as galvanized steel and high purity aluminum alloys. Moreover, a high-powered fiber-optic laser also offers excellent piercing capabilities for removing burrs from cut pieces. The laser machine produces a hole up to 12mm deep, and this hole is retained for ten seconds. In addition, high-speed airflow clears debris from the parts, making for faster cutting.

Laser/punch machines:

Punch/laser machines are highly flexible production tools that enable fabricators to achieve the desired edge quality at high cutting speeds. These machines can eliminate secondary processes and increase overall production flexibility with a single machine. Punch/laser machines are an ideal fit for many fabricators with the right mix of products. To learn more about punch/laser machines, read on to overview each machine’s features and benefits.

Kerf lasers:

In sheet metal fiber laser cutting, kerf lasers are used to cut thin metal layers or other materials that require a high-quality finish. They create a thin, focused beam of light through laser focusing optics. Once focused, the laser beam will melt, burn, or vaporize the material. The type of laser used depends on the materials being cut. These are different lasers that can help you cut fiber sheets easily.
