Abstract
We show that the stochastic dynamic approach to the decay of an unstable state can be developed in the form of an expansion which allows a systematic resummation of the usual perturbative series in the noise strength. The approach is applied to the laser transient radiation very close to threshold and is shown to give rather good results.Keywords
