| Abstract: | Effects of buffer gases on the laser-produced Al plasma were investigated in detail. Electron temperature under the different time-delay and Stark broadening of the spectral line under the different gas pressure was measured and thus the electron density of the plasma was obtained. According to the theory of the excitation caused by the electron collision, the experimental results are discussed. |

| Keywords: | Laser-produced Al plasma Electron temperature Stark broadening Electron density |
