摘要：

A 3-cm-long curved Ge slab target was irradiated by 1.053 mu m glass laser light with irradiance of 2.9 x 10(3) W/cm(2). The 19.6 nm laser line due to the 3p --> 3s, J = 0 --> 1 transition in Ne-like Ge ions was found to be polarized parallel to the target surface, with a degree of polarization of -53%. This polarization is accounted for by the anisotropy in the radiation trapping of the resonance line in an expanding plasma, which has a velocity gradient in the direction normal to the target surface.
