Pulsed Laser Cleaning Services
Non-Destructive. Eco Friendly. Paint, Rust removal from metal and wood items, large and small. Pulse laser cleaning is an efficient surface cleaning method based on laser technology. It uses a short-pulse laser beam with high energy density to irradiate the target surface, so that pollutants, oxide layers, or coatings are evaporated or peeled off in a very short time.
Compared with traditional cleaning methods (such as chemical solvent cleaning and mechanical polishing), pulse laser cleaning has the advantages of non-contact and no consumables, and is particularly suitable for scenarios with high requirements for cleaning accuracy and material protection.
THE TECHNOLOGY
Benefits
Pulsed laser cleaning is an effective method for cleaning wood surfaces without damaging the underlying material. Here are some key points:
-
Non-abrasive: Pulsed lasers minimize heat transfer, preventing damage to the wood fibers.
-
Time Saver: Can clean in minutes vs. hours of effort
-
Applications: It is commonly used for cleaning furniture, antique woodwork, and historical artifacts.
What Makes a Laser “Pulse”
A pulse laser does not emit a continuous beam but rather delivers laser energy in discrete bursts or pulses. Pulse durations can range from nanoseconds (10⁻⁹ seconds) to femtoseconds (10⁻¹⁵ seconds) in ultrafast laser systems. In this cleaning process, nanosecond or picosecond pulse lasers are commonly used. These short pulses deliver extremely high peak power for a brief moment, causing an intense interaction with contaminants or surface films. Pulse lasers are thus highly suited to processes like ablation, where precise material removal is desired without significant thermal conduction into the substrate.

Non-Contact Process and Minimal Substrate Damage
-
One of the greatest advantages of pulse laser cleaning is its non-contact nature. Traditional cleaning methods like abrasive blasting or chemical etching require physical contact or chemical reaction with the substrate, potentially harming delicate surfaces or introducing micro-scratches.
-
By contrast, a laser beam does not mechanically abrade the surface. The cleaning action is driven purely by light absorption, minimizing physical wear and tear.
-
The short pulse duration restricts heat flow into the material, resulting in less distortion, oxidation, or other thermal effects.

How does the Laser affect materials?
-
Laser cleaning is designed to be non-abrasive and non-contact, meaning it does not damage or alter the underlying material. The laser selectively removes only the contaminants, preserving the integrity and quality of the surface. This is particularly important for applications involving delicate or high-value materials, such as in aerospace, electronics, and cultural heritage conservation
