Measurements of Plasma Electron Temperature Utilizing Magnesium Lines Appeared in Laser Produced Aluminum Plasma in Air
LIBS Self Absorption Mg-Lines Plasma Parameters
2013/1/30
We have utilized the relative intensity of magnesium lines originated from the Mg I at 285.2 nm and Mg II at 280.27, 279.55 nm to measure the plasma electron temperature. The plasma was produced via i...
Energy Coupling Rate in Aluminum Welding by CO2 Laser and Nd:YAG Laser
Nd:YAG laser CO2 laser Coupling rate
2009/6/9
The energy coupling rate during welding of Al-Mg-Si alloys with a CO2 laser and a Nd:YAG laser was measured calorimetrically. The coupling rate obtained with the Nd:YAG laser was higher than that with...
