The Role of the Plasma during Laser-Gas Laser-Metal Interactions.
Abstract
The regime of CW laser-plasma-target interactions at intensities below 10 million W sq cm has been overlooked except for a few studies of gas assist configurations. The recent advances in industrial laser material processing and modeling efforts warrant a detailed study of laser-plasma-target interactions. The 10 KW CW CO2 laser facility has been used to study both pure gas and metal gas plasmas. Spectroscopic diagnostics have been applied to measure temperature in the plasma core where local electron temperatures are in excess of 10,000 K.
