Laser Marking Machine Marking The Effect Is Better

- May 05, 2017 -

Because semiconductor diode only sends a wavelength of light, so it pumps produced by the laser monochrome better, the laser mode is better, good laser mode will make the laser focused light spots smaller, more concentrated energy, achieve better marking effect;

Semiconductor and lamp-pumped lasers are used ND:YAG (neodymium-doped yttrium aluminium garnet) crystals as laser-generated materials, which can convert 808nm of visible light to 1064nm of invisible lasers, but another more critical factor of the output laser is the pumping source of the crystal rod output laser, the semiconductor pump is the use of semiconductor diode to emit 808nm of light waves; lamp pumps are pumped by the light emitted by krypton lamps, but the spectra of the light emitted by krypton lamps are wider, Just at the 808nm there was a slightly larger spike, and the light of other wavelengths turned out to be useless heat.
