摘要：

The angular distributions of laser ablated species generated from a colossal magnetoresistant metal-oxide Pr0.67Sr0.33MnO3 at 532 and 355 nm have been investigated by an angle- and time-resolved quadrupole mass spectrometric technique. It is found that the angular distributions of ionic and neutral ablated species vary distinctly with respect to the kinds of the ablated species as well as the laser fluence. For the laser ablation of a dense target at a moderate fluence, the angular distributions of the ablated species can be described by a cos(n) theta or a bicosine function a cos theta+(1-a)cos(n) theta.
