Laser Vaporization

High power density laser beam heating, surface temperatures to the boiling point temperature the speed is so fast enough to avoid melting from heat, so some material vaporize into steam disappeared, some materials as ejecta from the bottom of the slit is blown away by auxiliary gas flow. Some molten material such as wood, carbon materials and some plastic is cut to shape by the vaporization method.
Vaporization process, the steam take melted particles and scour debris, forming holes. Vaporization process, about 40% material into the steam disappeared, and 60% of material is in the form of droplets flow away.
