1. Introduction to laser cleaning
1.1. What is Laser Cleaning?
1.1.1 Definition of laser cleaning
Laser cleaning is a cleaning technology that utilizes a high-energy laser beam to irradiate the surface of an object, thereby removing contaminants, oxidized layers, paints and other impurities. Laser cleaning technology is characterized by non-contact, high precision and environmental protection, and is suitable for a wide range of materials and application scenarios. It vaporizes or strips contaminants through instantaneous high temperatures without causing damage to the substrate.
1.1.2 Working principle of laser cleaning
The working principle of laser cleaning is based on the high energy density and short pulse action of the laser beam. When the laser beam irradiates the surface of an object, its energy is absorbed by the contaminants on the surface, causing the contaminants to heat up rapidly and undergo thermal expansion, vaporization or decomposition, and then fall off from the surface. Selective cleaning can be achieved because the laser beam can precisely control the range of action.

2. How laser cleaning works
2.1 Scientific principles of laser cleaning
2.1.1 Interaction of the laser with the material
The core principle of laser cleaning is to utilize the interaction between the laser beam and the material surface. When a high-energy laser beam irradiates the surface of a material, its energy is rapidly absorbed by the contaminants on the surface, resulting in a sharp rise in the temperature of the contaminants. Depending on the nature of the contaminant, this rapid warming may cause vaporization, ablation, or thermal expansion of the contaminant, which can cause it to peel away from the material surface.
2.1.2 Thermal and Optical Pressure Effects
There are two main effects involved in the laser cleaning process: the thermal effect and the optical pressure effect. Thermal effect refers to the laser energy into thermal energy, so that the pollutant temperature until the decomposition or vaporization. The photocompression effect refers to the impact of laser photons on the contaminant, causing it to be stripped from the surface. These two effects work together to effectively remove contaminants from the surface without damaging the substrate.
2.1.3 Advantages of non-contact cleaning
Laser cleaning is a non-contact cleaning method, which means that no mechanical force is applied to the material surface during the cleaning process. Compared to traditional chemical and mechanical cleaning methods, laser cleaning reduces wear and damage to the material and avoids environmental contamination from chemicals. This makes laser cleaning particularly suitable for applications requiring high precision and cleanliness.

In addition, modern laser cleaning equipment is usually equipped with a variety of safety protection measures, such as safety interlocking devices, protective barriers and emergency stop buttons, to ensure the safety of operators.
Chemical Cleaning: During the chemical cleaning process, operators need to contact and handle various chemical reagents, there are chemical burns, inhalation of harmful gases and other safety risks. Even with protective measures, it is difficult to completely avoid these risks. In addition, volatilization and leakage of chemical reagents may cause harm to the working environment and surrounding personnel.
5.1.3 Cleaning effect
Laser cleaning: Laser cleaning is characterized by high efficiency and precision, and can selectively clean different materials and pollutants. Laser cleaning can remove rust, oxidized layer, paint and other pollutants, while protecting the substrate from damage. Laser cleaning is particularly suitable for application scenarios that require high precision and cleanliness.
Chemical Cleaning: The effectiveness of chemical cleaning depends on the type and concentration of the reagent, with different reagents having different effects on different contaminants and materials.
