| Abstract: | Time and Spatial resolved measurments of all plasma emission produced by pulsed Nd:YAG laser ablation of metal Cu in different backing gas are repored. The effects of different backing gas pressure over the range of 13 Pa to 101 3 kPa on all plasma emission intensity is studied. The results are qualitatively explained using a simple model based on plasma emission arising from electron collion energy transfer and recombination of the electron and ion in the plasma. |
