| 摘 要： | We report an effect of enhanced emission of laser generated plume in gas ambi-ent.Nonreactive argon gas was used in the experiment of UV laser ablation of copper plate.The emission of Cu atoms from the plume was increased more than the times.The emission in-tensity is sensitive to the gas pressure,but in a certain region of gas pressure,the enhanced ef-fect can be controlled stably.For the emission lines from other element,Zn,in the plume,the intensities are subjected to the same factor of increasement.

| Abstract: | We report an effect of enhanced emission of laser generated plume in gas ambient. Nonreactive argon gas was used in the experiment of UV laser ablation of copper plate. The emission of Cu atoms from the plume was increased more than the times. The emission intensity is sensitive to the gas pressure, but in a certain region of gas pressure, the enhanced effect can be controlled stably. For the emission lines from other element, Zn, in the plume, the intensities are subjected to the same factor of increasement. |
