What is a Fiber Laser Cleaning Systems

A laser cleaning system is a specialized machine that utilizes a high-powered laser beam to remove contaminants, coatings, rust, and other unwanted materials from various surfaces without causing any damage to the underlying substrate. 

Laser Cleaning Process

  • The laser beam delivers thousands of focused laser pulses per second onto the contamination layers, effectively ablating and removing them from the surface.
  • The process is non-contact, meaning the laser beam does not physically touch the surface being cleaned, reducing the risk of damage or wear.
  • It is an eco-friendly cleaning method that does not involve any chemicals, abrasives, or blast media, making it environmentally friendly and safe for operators.

Types of Laser Cleaning Systems

  • Handheld/Manual Systems: Portable and flexible solutions ideal for cleaning projects with varying locations, part numbers, and unique geometries. Operators manually control the laser beam.
  • Automated Systems: Integrated with robotics and laser processing cells, these systems automate regular cleaning processes for high-volume production lines.

How Do Fiber Laser Cleaning Systems Work?

The fiber laser generates nanosecond-length pulses of a high-density laser beam, which is then delivered to the workpiece surface through an optical fiber cable.When the laser beam strikes the surface, its energy is absorbed by the contaminant layer, causing it to vaporize, ablate, or separate from the substrate through processes like light peeling, plasma impact, or vibration. The laser’s parameters like power, pulse duration, and frequency are precisely controlled to ensure effective cleaning without damaging the underlying material.

Power Levels

  • Low Power (20W – 100W): Suitable for gentle cleaning, small products, or applications requiring precision.
  • Mid Power (200W – 500W): Designed for moderate-sized areas, mold cleaning, oxide removal, and aircraft paint removal.
  • High Power (1000W – 3000W): Capable of handling larger areas, thick coatings, and heavy-duty cleaning tasks like rust removal and surface preparation for welding.


  • Surface preparation for welding, painting, or coating adhesion.
  • Rust, corrosion, and oxide removal from metals.
  • Paint, grease, and coating removal from various substrates.
  • Cleaning and restoration of historical artifacts, buildings, and artworks.
  • Decontamination in nuclear and aerospace industries.

Benefits of Fiber Laser Cleaning Systems

  • Precise and selective cleaning without damaging the underlying substrate.
  • Non-contact process, eliminating the need for abrasives, chemicals, or mechanical force.
  • High speed and efficiency, suitable for automated production lines.
  • No consumables or waste products, leading to lower operating costs.
  • Environmentally friendly and safe for operators.
  • Versatile and suitable for cleaning metals, plastics, ceramics, glass, and other materials.
  • Improved surface quality and adhesion for subsequent processes like painting, coating, or bonding.

How Choosing a Fiber Laser Cleaning System

There are a number of factors to consider when choosing a fiber laser cleaning system, including:

  • Power: The power of the laser system will determine the types of contaminants that can be removed and the speed of cleaning.
  • Pulse type: There are two main types of pulses used in laser cleaning: continuous wave (CW) and pulsed. CW lasers are better for removing large areas of contamination, while pulsed lasers are better for more delicate cleaning tasks.
  • Portability: Handheld laser cleaning systems are available for portable use, while larger systems are designed for stationary use.
  • Safety: Fiber laser cleaning systems can emit powerful beams of light, so it is important to choose a system that meets safety standards and to use appropriate safety gear when operating the system.

Can Laser Cleaning Systems Be Used on All Types of Materials

No, laser cleaning systems cannot be used on all types of materials. While laser cleaning is versatile and can clean a wide range of materials, there are certain materials and situations where it may not be suitable or could potentially cause damage.


Fiber laser cleaning systems are a powerful and versatile tool that can be used for a variety of cleaning applications. When choosing a system, consider the power, pulse type, portability, and safety features of the system.
