The reason why radio frequency (RF) laser marking machines cannot mark on metal surfaces is due to the laser's wavelength and beam characteristics, which are not suitable for metal material treatment. Metals typically
require higher power and an appropriate wavelength of laser to achieve marking. The wavelength of RF laser marking machines has a high reflectivity on metal surfaces, making it challenging to generate sufficient heat for
marking. For marking on metals, lasers with wavelengths suitable for metal absorption, such as fiber lasers or other high-energy lasers, are commonly used.
