A new method using the laser-induced fluorescence method was developed to measure the spatial electron density distribution. The local electron density can be determined by observing the intensity ratio of the laser- to the collision-induced fluorescence. A spatial electron density distribution of a helium plasma (T_e ∿ 6eV, n_e : 10^<11-12>cm^<-3>) has been determined by observing the He (3^1P ⇾ 2^1S) laser-induced fluorescence and the He (3^1D ⇾ 2^1P) collision-induced fluorescence due to the He (3^1P ⇾ 3^1D) collisional transfer process with electrons. The comparison of the result with that of a conventional method proves this new method is of practical use in the space-resolved measurements of plasma electron density.
