Enhancement of long wavelength preheating in dual-beam laser induced breakdown spectroscopy

Enhancement of long wavelength preheating in dual-beam laser induced breakdown spectroscopy

Dual-beam laser induced breakdown spectroscopy (LIBS) is more sensitive than conventional single-pulse LIBS. A combined configuration of Nd:YAG and CW- CO2 lasers is used to improve the emission intensity of LIBS. The plasma of Al sample was observed under CW-CO2 laser and Nd:YAG laser excitation. T...
