Investigation of the mechanism of spectral emission and redshifts of atomic line in laser-induced plasmas

In low-temperature plasmas, the specific emission mechanism and the evolvement of the continuum and isolated lines are quite complex, which are described in detail. The calculations from the Stark-broadening measurement of individual lines show the density to be of the order of magnitude of 1018 cm−3. It is seen that the redshifts of spectral lines detected in this experiment are influenced by the electron density. A possible reason for this is given.
