What Is A Fiber Laser Cutter and How It Works

Every laser system is built with a “gain medium,” which is a material that can amplify light. Also known as a “laser medium” or “active medium,” gain mediums can be solid, gas, or liquid, and these different materials affect the system’s beam qualities. Depending on what kind of material a laser system uses as a gain medium, the system will fall under one of these three categories:

1. Solid-state laser
2. Gas laser
3. Liquid laser

To create a beam, laser systems use “pump sources” (i.e., external power supplies) to energize the gain medium through a process called “pumping.” Laser systems can use various pump sources, including flashlamps, electrical currents, and radio frequencies. By pumping the gain medium, laser systems excite the material into releasing photons.

On a basic level, laser systems take these released photons and use mirrors to increase energy and form a beam. Once the beam is strong enough, the system releases it toward the substrate to complete the intended application.

Fiber Laser Systems: Principles and Material Compatibility

With these details in mind, let’s explore how fiber laser systems function and their capabilities.

Fiber lasers are solid-state devices using fiber optic cables doped with rare earth ions to amplify light. Here’s how they operate:

• Energy Injection: A laser diode or similar source injects energy into the optic fiber, exciting the rare earth ions to emit photons.
• Photon Amplification: The emitted photons bounce within the fiber, increasing energy.
• Beam Formation: Photons are funneled to a mirrored optical cavity, forming a concentrated beam.
• Material Interaction: The focused beam is directed at the material for marking, engraving, or cutting.

These principles allow fiber lasers to efficiently handle a variety of materials with high speed and precision. Fiber, CO2, and UV lasers each operate at different wavelengths, affecting their compatibility with various materials. Here's a general overview:

This variety in laser systems ensures suitability for diverse industrial applications, each excelling in specific material interactions.

Cutting, Marking, and Engraving: 3 Basic Uses of Fiber Laser Cutter

The chart above highlights that fiber laser systems exhibit exceptional compatibility with a variety of materials, particularly metals and plastics. These systems are predominantly used by companies working with:

• Metal sheets
• Metal pipes
• Aluminum cans, foil, and bottles
• Plastic bags
• Plastic bottles
• Rigid plastic materials

Fiber laser systems can be employed to cut, mark, or engrave these materials depending on the company's specific operational needs. However, not all fiber laser systems are capable of handling every type of application effectively.

While fiber laser systems are versatile, the requirements for cutting, marking, and engraving differ significantly. Cutting is the most demanding application and relies on several crucial factors. The two key elements are:

• 
  

  System Power: The power of fiber laser systems is typically measured in watts (W), with models ranging from 10W to 10,000W. Higher power systems are more effective at cutting various materials. For instance, a 10W system is not suitable for cutting, while a 40W system can cut thin plastic sheets. A 200-500W system is capable of cutting thicker plastic, and a 500W system can handle thin metal sheets.

  
  
• 
  

  Material Thickness: The thickness of the material determines the power required for cutting. Thin plastic sheets can be cut with a more affordable 100W system, whereas thicker metals, such as those used in pipes and construction materials, require a minimum of 1,000W for reliable cutting performance.

  
  

Given the high power requirements for cutting, many fiber laser systems are primarily designed for marking and engraving applications. For these tasks, different power levels are needed based on the material:

Marking and Engraving: To mark or engrave metal products, a minimum of 10W is required, with 50W being ideal for efficient and high-speed results. For plastics and other non-metallic materials, a 10W-20W system will generally suffice.

Regardless of whether you are working with metal or plastic, the more powerful and well-built your system is, the better your results. Consider the KRRASS Smart 3015 series fiber laser marking machine, for example.
