摘要：

The dynamics of various neutral particles during laser ablation of YBa2Cu3O7-x in the O-2 ambient gas is investigated using post ablation ionization mass spectrometry in combination with molecular beam technique. The O-2 environment is found to favor oxide cluster formation in the ablation plume. The pressure above similar to 100 mTorr results in a pulsating character of the plume expansion within a finite propagation distance.
