Laser-produced carbon plasma expanding in vacuum, a low pressure ambient gas (5 mTorr and 100 mTorr) and a nonuniform magnetic field is studied using fast photography. The temporal behavior of various plasma parameters, like velocity, electron density, electron temperature and intensity, is reported. In 5 mTorr air, the plasma breaks into slow and fast components. In the magnetic field, oscillations are observed in the plasma parameters.
