Laser coating – coating processing
Laser film
The laser film has the characteristics of high-energy laser transmission, and is usually made of composite materials such as PET. In laser cutting, it can effectively absorb laser power, avoid smoke and dust during cutting, and protect cutting materials from deformation and damage, thus improving cutting quality and efficiency. Dinghongrun The laser films of are Nd Yag laser film, CO ₂ laser film, and can also be customized for you according to application needs.
Nd Yag laser film
Nd Yag laser film is a kind of solid laser. Its activating material is yttrium aluminum garnet crystal (YAG crystal), which is doped with a small amount of neodymium (Nd). This kind of laser is called Nd Yag for short in English. It can generate pulse or continuous laser and emit infrared light of a specific wavelength, usually 1064nm. The principle of laser is that when electrons in atoms absorb energy, they transition from low energy level to high energy level, and then fall back from high energy level to low energy level, the released energy is released in the form of photons. Photon beam (laser) induced (excited), in which the photon optical properties are highly consistent. It is used in laser marking, laser welding, laser cutting, optical fiber communication, laser ranging, laser radar, laser weapons, laser records, laser correction, laser beauty, laser scanning, laser mosquito killer and LIF nondestructive testing technology.
CO ₂ laser film
The CO2 laser film has specific optical properties in a specific wavelength range, such as high reflectivity or high transmittance. The laser film is usually used on the mirror or window of the laser resonator to ensure efficient reflection and transmission of laser. The typical operating wavelength of the CO2 laser is 10.6 μ m, so the CO2 laser film will be designed to have excellent reflection performance at this wavelength. Such a film can reduce the loss of the laser in the resonator and improve the output power and efficiency of the laser. Used in mirrors or windows of laser resonators, spectroscopy, lidar, communication equipment, etc.
