摘要：

Second harmonic generation from the plasma density gradient induced by ponderomotive force was studied. Images of the second harmonic emission at the focal point, where the intensity was above 10(17) W/cm(2), were observed. These images strongly depended on the polarization of the pump pulse. The polarization of the second harmonic was the same as that of the pump pulse. Experimental results were well explained by the theoretical model. (C) 2002 American Institute of Physics.
