An experimental study on He-Ne laser (1.15 μ) under pulsed H.F. excitation reveals that there exist delay in oscillation build-up and a peak in the output at the beginning of oscillation. From qualitative discussions on the behavior of photon density and inversion density on the basis of coupled rate equations, these transient phenomena are shown reasonable. Contributions of various factors related to lasing mechanism are clarified from numerical calculations of simplified rate equations by the use of electronic computers. Both loss terms for the photon and the inversion effect strongly the shape of the curve of the solution. The increase of the former produces an oscillating build-up, while the contribution of the latter is opposite. Resultant contribution of the loss terms is also analysed. A reasonable set of the coefficients is found to lead to a solution having the delay which agrees with the experiment.
