摘要：
Using Normaski polarization interference technique, the expansion process of a plasma generated by ultrashort laser pulses was optically diagnosed. Temporal resolved interferogram of the laser-plasma has been obtained. A strong pinch effect in the transverse dimension has been observed for a jet expansion of the laser-plasma. It is found that the pinch effect was due to the confinement of the magnetic fields generated in the laser-plasma.
