摘要：

Absolute density measurements of Na blow-off atomic beam were carried out with time of flight laser induced fluorescence. The preferentially used 1 μm Na layer was in situ evaporated on a glass plate. The velocity distribution of the blow-off neutrals was investigated as a function of the Nd laser fluence. The measurements showed that the blow-off beam contains two atomic packets with different propagation velocities in the laser range of 10-20 J/cm2 and one atomic packet elsewhere. The faster packet has a maximum total number of atoms at 3 J/cm2 and its velocity can be well fitted with a power function of the irradiance with v∼I0.29. © 1990.
