How To Choose Laser Cleaner?

Carbon dioxide laser is a gas laser that uses CO2 gas as its working substance. The interior is filled with CO2 gas and other auxiliary gases (helium and nitrogen and a small amount of hydrogen or xenon). It has good directivity, monochromaticity and frequency stability. Based on its unique wavelength, CO2 laser is the best choice for surface cleaning of non-metallic materials such as glue removal, coating removal, and ink removal.

Ultraviolet laser has short wavelength and high single photon energy, which can directly destroy the chemical bonds connecting materials. Material is stripped from the surface in the form of gas or particles. The heat-affected zone generated during processing is small, which has unique advantages in micro-manufacturing. Widely used in communications, optics, military, criminal investigation, medical and other industries and fields.

The working principle of a continuous fiber laser is that the pump light emitted by the pump source is coupled into the gain medium through a reflecting mirror. Since the gain medium is a fiber doped with rare earth elements, the pump light is absorbed, and the rare earth ions that absorb the photon energy generate energy. stage transition and achieve particle number inversion. The inverted particles pass through the resonant cavity and transition from the excited state back to the ground state, releasing energy and forming a stable laser output. The biggest advantage is that it can continuously emit light. Suitable for occasions where the damage to the base material is not high.

Pulse laser cleaning machines use high-energy, high-frequency pulse laser beams to instantaneously heat and cool the surface of objects, forming instantaneous temperature gradients and thermal stress, so that contaminants and thin coverings can fall off the surface. The principle is that through short-term, high-energy irradiation of laser pulses, high temperature and high pressure are instantly generated, which quickly evaporates or crushes pollutants to achieve a cleaning effect.

It can be used to remove various contaminants, such as paint, oxides, welding slag, etc., and is widely used in various industries, such as automobile manufacturing, electronic equipment, aerospace, semiconductor processing, etc. Because pulse laser cleaning has the characteristics of high energy and short action time, it is suitable for cleaning objects with high surface requirements.
