초록
During measurement of atomic hydrogen in a silane plasma using two-photon excited laser induced fluoresecence, laser-induced dissociation of the gas was observed. This was investigated untill conditions for the input laser fluence were determined where the effect was negligible. A measurement of the atomic hydrogen distribution was then performed within the limits of these conditions. Absolute density determinations showed atomic hydrogen densities of around
