In this paper, we examine the factors minimizing the transient spikes in the evolution of a laser pulse. Our study is based on a mathematical model simulation of the laser implemented in Matlab Simulink. A model of the flash lamp excitation circuit is also included in the overall laser model. It allows us to show the correlation between the characteristics of the Q-CW laser pulse mode and the various physical parameters of the oscillator. The model proposed is applicable to the case of a single- or multiple-mesh pulse-forming network (PFN) of the flash lamp excitation current. The spikes in the laser pulse are substantially reduced by using the pulse doubling pump (PDP) technique. The simulations results give a clean laser pulse in a single mesh and in five meshes.
