The influence caused by metal laser cutting machine for metal is also very big, general metal to light the role of the reaction is strong absorption and strong reflection.
Strong absorption refers to the small long wavelengths, orders of magnitude of penetration depth of less than, to preach in metal electron incident light wave energy can be converted to the joule heat, but due to the penetration depth is small, so the total energy dissipation and rarely electronics.
Strong reflection is because of the skill books surface reflectivity is much taller than the transparent medium, the majority of the incident energy is the surface of the metal reflection.
Various metal because of the free electron density is different, the ability of reflection waves are also different.
In general, the greater the density of free electrons, which is the greater the conductivity, the higher the reflectivity.
