< p > 1, metal materials by laser cutting almost all metals at room although temperature on the infrared wave energy is very high reflectivity, but the emission in far infrared beam CO2 laser or 10.6 um a successful application in many metal laser cutting practice. Metal on initiation of UM laser beam absorption rate 10.6 from 0.5% ~ 10% only however, when, with a power density of more than 106w/cm2 focused laser beam irradiation to the metal surface, but it can in the microsecond time soon so that the surface begins to melt. The absorption rate of most metals in the molten state has risen sharply, which is generally improved by 60%~80%.
non metal materials by laser 2. Cutting
10.6 um wavelength of CO2 laser Beam can easily be on material absorption, thermal conductivity and low evaporation temperature and the absorption of the beam is almost the entire input material internal and in the IMDM spot instant vaporization, forming into the hole, the virtuous circle in the cutting process.
