Laser wavelength basics
What is laser wavelength
Laser wavelength is the space between two peaks in a light wave. This wave comes from a laser. You can think of wavelength as the laser’s “color.” Most cleaning lasers use light you cannot see. The wavelength shows where the laser fits in the electromagnetic spectrum. When you clean with a laser, the wavelength affects how the light works with materials. Some materials soak up certain wavelengths better. This changes how deep the laser goes. It also changes how much energy the laser gives.
Note: Picking the right wavelength helps you clean well. It also keeps the surface under safe.
Why wavelength matters in cleaning
The wavelength is important when you use a handheld laser cleaning machine. It helps you remove dirt, rust, or paint. Shorter wavelengths have more energy. They break up dirt with less heat. This helps you avoid burning or melting the surface. This is called photochemical ablation. Longer wavelengths have less energy. They spread heat more and work by photothermal ablation. This means they heat up the dirt until it comes off.
Here is a simple table to show how wavelength affects cleaning:
| Wavelength Type | Energy Level | Cleaning Method | Best For |
|---|---|---|---|
| Shorter (e.g., UV) | High | Photochemical ablation | Thin layers, delicate |
| Longer (e.g., IR) | Lower | Photothermal ablation | Thick rust, tough dirt |
You need to think about the material and the kind of dirt. Some surfaces bounce certain wavelengths away. This means the laser may not work as well. If you pick the right wavelength, you clean better. You also keep your equipment safe.
Tip: Always check the material and the dirt before you pick the laser wavelength for cleaning.
Typical wavelengths in handheld laser cleaning machines
1064nm fiber lasers
Many handheld laser cleaning machines use the 1064nm wavelength. This wavelength is good for cleaning metals like stainless steel, aluminum, iron, and carbon steel. It cleans well but does not hurt the surface. The 1064nm fiber laser sends energy through a fiber optic cable. You can use it to take off rust, strip paint, and clean molds.
