Basic investigations for laser microanalysis. IV: The dependence on the laser wavelength in laser ablation

The fourth harmonic wavelength at 266 nm as well as the fundamental radiation at 1.06 mu m of a pulsed Nd:YAG laser has been used for ablation of solid samples. Using different buffer gases and different samples, the ablated masses and plasma temperatures obtained with the two different laser wave-l...

Description
Summary:The fourth harmonic wavelength at 266 nm as well as the fundamental radiation at 1.06 mu m of a pulsed Nd:YAG laser has been used for ablation of solid samples. Using different buffer gases and different samples, the ablated masses and plasma temperatures obtained with the two different laser wave-lengths are compared. The analytical application of 266 nm laser pulses is studied by the measurement of Al and Mn in steel and borax-glass (Na sub 2 B sub 4 O sub 7 ) samples. Copper is also analyzed.
