The Main Advantage of Picosecond Laser Cutting Machine
The two main advantages of picosecond lasers cutting machine than nanosecond lasers are:
1.cold processing, ultra-short pulse, release energy in the picosecond time, for decomposing material, do useful work, energy far more than absorb threshold of a variety of materials, heat affected area small to negligible, no microcracks, remelting and recrystallization;
2.deep processing, neither carbon dioxide and ordinary infrared laser light heat of the physical processing, but not nanosecond ultraviolet laser photochemical reaction to destroy the molecular structure of the molecular processing, but the bombardment of electrons to produce nucleus between the Coulomb force to remove the material of the atomic processing. There is little choice for the material, which can be deep in most materials.
