摘要
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 wavelengths are compared. The analytical application of 266-nm laser pulses is studied by the measurement of aluminium and manganese in steel and borax-glass (Na2B4O7) samples.
