We investigated the angular dependence of atomic and ionic debris from CO 2 and YAG laser-produced tin plasmas. Several diagnostic techniques were employed for this study including a Faraday cup, witness plates and subsequent x-ray photoelectron spectroscopic analysis, optical emission spectroscopy etc. It was found that the debris emission from the Nd:YAG laser-produced plasmas fell sharply from the target normal. In contrast, the debris emission from the CO 2 laser-produced plasmas was almost constant at short angles from the target normal. Our results also indicated that the plasma produced by the CO 2 laser emitted less atomic and ionic debris compared to a plasma produced by Nd:YAG laser. |
