Abstract
The electron density and the absorption coefficient of the laser induced vapour/plasma as well as the geornetry of the expanding plasma are investigated by the beam deflection. The electron density is examined in dependence on different parameters. The results obtained by beam deflection are compared to those of optical emission spectroscopy. By comparing both methods of measurement it can be claimed that a local thermal equilibrium (LTE) is present in the vapour/plasma.
