Characterization of Expanding Laser Plasma Produced by Laser Ablation
This work is devoted to characterizing the plasma produced by nanosecond laser ablation. The expanding plasma was generated by the interaction of a home made XeCl excimer laser with a Cu target. The time-of-flight method was utilized as diagnostic tool of the plasma charged particles. By this method, in fact, we were able to measure the ion and electron currents, the charge-states and the energ...

متن کاملNanosecond polarization-resolved laser-induced breakdown spectroscopy.
It is shown that the continuum emission produced in the ablation of an Al target with nanosecond laser pulses is much more strongly polarized than the discrete line emission. This effect may be utilized to improve the resolution of the laser-induced breakdown spectroscopy spectrum by using a polarizer to filter out the continuum background. The effects of laser fluence and focal position are al...

متن کاملInvestigations on nanosecond laser produced plasma in air from the multi-component material YBa2Cu307
The laser produced plasma from the multi-component target YBa2Cu307 was analyzed using Michelson interferometry and time resolved emission spectroscopy. The interaction of 10 ns pulses of 1.06 #m radiation from a Q-switched Nd:YAG laser at laser power densities ranging from 0.55 GW cm 2 to 1.5 GW cm 2 has been studied. Time resolved spectral measurements of the plasma evolution show distinct fe...
