Abstract :
We investigated the expansion features of laserproduced Al plasma in the presence of 0.8 T magnetic field. Fast-gated photography was used to record 2-D snapshots of plasma at various moments during its expansion. The slowing down and stopping of the plasmas were observed at all laser irradiance levels used (3-10 GW·cm-2), however, increasing convexity of the plasma periphery was noticed at higher irradiance levels.
