Analysis of pulse smoothing by multi-pulse interference in time domain

In the inertial confinement fusion (ICF) system, there exists a special requirement of waveform of the laser pulse(a shaping pulse with a width of ns). This paper proposes a coherent pulse stacking method which can make the output stacking pulse meet the requirement of the ICF. It theoretically and technologically investigates the multi-pulse interference in time domain, derives the range of time detention (about the width of the single Gaussian pulse) and the phase control accuracy of neighbor pulses to achieve the requirement of smoothing.
