What Kind Of Laser Is Used For Cleaning?

Laser cleaning is typically performed using pulsed or continuous-wave (CW) fiber lasers, solid-state lasers, or sometimes CO2 lasers, depending on the specific cleaning requirements and materials being processed. Each type of laser has its advantages and is suited for different applications:


1. Pulsed Fiber Lasers: Pulsed fiber lasers are one of the most commonly used types of lasers for cleaning applications. They are highly efficient and can produce short, intense bursts of laser energy, making them effective at removing contaminants, rust, paint, and other unwanted surface layers. Pulsed lasers are known for their precision and controlled material removal.


2. Solid-State Lasers: Solid-state lasers, such as Nd:YAG (neodymium-doped yttrium aluminum garnet) lasers, are also used for laser cleaning. These lasers are versatile and can be effective in various applications, including rust removal, paint stripping, and surface preparation.


3. CO2 Lasers: CO2 lasers are used for specific cleaning applications, particularly when the material’s surface is highly absorbent to the CO2 laser wavelength. They are suitable for tasks like cleaning organic materials, rubber, or certain types of contaminants.


The choice of laser type depends on factors such as the type of material to be cleaned, the contaminants or unwanted layers on the surface, and the desired outcome. Laser cleaning technology offers high precision, minimal material waste, and the ability to work on delicate or sensitive materials, making it an effective and efficient method for various industries, including manufacturing, conservation, and maintenance.
