1.4SELECTIVE EVAPORATION

Different materials have varying absorption rates for specific wavelengths of laser energy. When the absorption rate of surface contaminants on the material is higher than that of the substrate, laser irradiation can rapidly elevate the temperature of the contaminants above their melting point, causing vaporization.

The surface interface vaporization phenomenon generated by this process does not cause any damage to the substrate since it does not reach the melting point of the substrate.

Typical Applications：Tire Mold Cleaning  /  Laser Paint Stripping  /  Carbon Deposits Removal

2.INSTANTANEOUS SURFACE THERMAL EFFECT

When the laser pulse rapidly scans the surface of the workpiece, the temperature in that area momentarily increases and then decreases, generating thermal elastic pressure.

Due to the different coefficients of thermal expansion between the adhesive and the substrate, it results in uneven surface stress distribution, leading to the detachment of the adhesive from the substrate.

Typical Applications：Laser Rust Removal

3.IMPACT EFFECT

The high energy density of pulsed laser results in the vaporization of adhesives, creating an instantaneous high temperature in their vicinity and ionizing the vaporized material, generating a plasma. With continuous laser irradiation, the plasma locally generates high temperature and pressure, further producing shockwaves that compress and fracture the underlying material at a microscopic level. When the laser pulse stops, the plasma generates an instantaneous negative pressure, thereby removing the particles created by compression of the adhesives.

Typical Applications：Laser Removal Of Metal Oxide Layers
