Abstract
The dynamics of various neutral particles during laser ablation of YBa 2Cu3O7-x in the O-2 ambient gas is investigated using post ablation io nization mass spectrometry in combination with molecular beam techniqu e. The O-2 environment is found to favor oxide cluster formation in th e ablation plume. The pressure above similar to 100 mTorr results in a pulsating character of the plume expansion within a finite propagatio n distance.
