With the continuous development of industrial automation and environmental protection regulations, the importance of laser cleaning technology has become increasingly prominent. Efficient, clean and green laser cleaning solutions are favored by more and more companies and industries. The market has a strong demand for low-energy, pollution-free cleaning technology, and laser cleaning technology is developing rapidly in the direction of intelligence, automation, and efficiency.


This study aims to conduct an in-depth analysis of the factors that affect laser cleaning efficiency, in order to provide theoretical basis and practical guidance for further improving the performance and application effects of laser cleaning technology. By understanding and optimizing these factors, companies can be helped to achieve higher economic benefits and environmental protection effects during the cleaning process, thereby promoting the widespread application and sustainable development of laser cleaning technology.

How Laser Cleaning Works

The working principle of laser cleaning is mainly based on the interaction between laser and contaminants. The specific process can be divided into the following steps:


Laser emission: The laser cleaning equipment emits a high-intensity laser beam with a specific wavelength and pulse duration, which can selectively act on the dirt or coating on the surface to be cleaned.

Light absorption: The surface of the contaminant or coating absorbs the laser energy. Different materials have different absorption capabilities for lasers. Contaminants usually have good light absorption characteristics and can therefore absorb the energy of the laser.

Thermal effect: After the laser energy is absorbed, the temperature of the contaminant rises rapidly. Due to the sharp increase in temperature, the contaminant may undergo phase changes, such as rapid evaporation, melting or decomposition. At the same time, the pulse time and energy density of the laser can control the range of thermal action to reduce the impact on the substrate.

Removal of contaminants: As the temperature rises, the contaminant reaches the limit of its material strength, eventually causing it to break, peel off or be vaporized, thereby detaching from the surface of the substrate. This process is non-contact, reducing mechanical wear on the substrate.

Gas and particle emissions: The removed pollutants or coatings will be released into the air in the form of gas, vapor and tiny particles. Depending on the equipment configuration and protection measures, these substances may be extracted through the exhaust system to ensure a safe and clean working environment.


Through the above series of processes, laser cleaning can efficiently and accurately remove all kinds of dirt and coatings while maintaining the integrity of the substrate. This technology is widely used in industrial production, cultural relics protection and equipment maintenance, and is therefore increasingly valued and adopted.

Main Factors Affecting Laser Cleaning Efficiency

1. Laser parameters

Laser wavelength: There are significant differences in the absorption efficiency of lasers with different wavelengths for different materials. Generally speaking, short-wavelength lasers (such as ultraviolet lasers) have stronger absorption capabilities for organic materials, while long-wavelength lasers (such as infrared lasers) are more suitable for metallic materials. Choosing the appropriate wavelength can improve cleaning efficiency.

Laser power: Laser power directly affects the cleaning rate and effect. Higher power generally means greater energy output, resulting in more effective removal of contaminants. However, excessive power may cause damage to the substrate, so a reasonable choice in power setting is required.

Pulse frequency: The pulse frequency affects the number of laser shots per unit time. A higher pulse frequency can increase the energy accumulation per unit time, thereby increasing the thickness of contaminant removal, but the heat dissipation of the material must also be considered to avoid overheating damage.


2. Beam quality and focus characteristics

Beam quality: The beam quality of the laser affects the focusing effect of the laser. A high-quality beam can be focused into a smaller point, thereby increasing the laser energy density and enhancing the cleaning effect.

Focus size: The size of the focus diameter directly affects the energy concentration of the laser. A smaller focus can improve cleaning efficiency and cleaning depth, but may limit the area processed.

Depth of focus: Depth of focus is critical to adapting to different surface morphologies. Large depth of focus accommodates irregular surfaces and maintains consistent cleaning.

3. Characteristics of cleaning materials

Types of contaminants: Different types of contaminants (such as oil, rust, coatings, etc.) can respond significantly differently to the laser cleaning process. Therefore, it is very important to select appropriate laser parameters to target specific contaminants.

Surface condition: The surface roughness and smoothness of the material will directly affect the laser adhesion and cleaning effect. Smoother surfaces are generally easier to clean, while rough surfaces may cause dispersion of laser energy and reduce cleaning efficiency.


4. Cleaning distance

Distance between laser and work surface: The ideal laser working distance is critical to cleaning efficiency. Too far a distance will result in loss of laser energy, while too close a distance may cause thermal damage to the material. Therefore, determining the optimal cleaning distance is very important to improve the cleaning effect.


5. Scan speed and strategy

The speed at which the laser scans contaminants: Different scanning speeds will affect the laser action time and cleaning effect. Slower speeds can provide more energy accumulation, thereby improving cleaning depth and effectiveness, but will reduce work efficiency.

Selection of different cleaning paths and strategies: Reasonable cleaning path design and strategies can improve the efficiency and thoroughness of cleaning and avoid omissions and repeated cleaning.


6. Environmental factors

Ambient temperature and humidity: Environmental conditions affect the efficiency and effect of laser cleaning. High temperature and high humidity may cause instability of the laser beam, thereby affecting cleaning performance.

Particulate matter and flow in the air: Dust, particles or airflow in the air may interfere with the laser cleaning effect, resulting in a reduction in cleaning effect. Choosing a suitable working environment can improve cleaning quality and efficiency.


The comprehensive analysis of the above factors is of great significance for optimizing the laser cleaning process and improving its efficiency and cleaning effect. Ideal laser cleaning conditions can not only improve work efficiency, but also effectively protect the structural integrity of the material being cleaned. Click here for more information
