Laser and Material Interaction: The Keyhole Effect

FrankTang

Definition of Keyhole: When the irradiance exceeds 10^6 W/cm^2, the material surface melts and evaporates under the influence of the laser. If the evaporation rate is sufficiently high, the vapor recoil pressure generated can overcome the surface tension of the liquid metal and gravity, displacing some of the liquid metal...
