Paper Abstract

We have developed a pulse-shaping system of the partially coherent light with angular spectral dispersion for the application to inertial confinement fusion experiment. The angular spectral dispersion is essential not only to the efficient frequency conversion but also to the reduction of the medium mode irradiation nonuniformity. The pulse-shaping system is based on the temporal stacking of pulses using optical fiber couplers and variable attenuators. This system enables us to generate arbitrarily pulse-shaped partially coherent light with a fast rise time of approximately 50 ps. Using this system we have demonstrated a 1.6-ns flat-top pulse with a 200-ps picket pulse under the operation condition of approximately 1000 J/beam at the fundamental wavelength, and this pulse is being supplied in the current implosion experiment with the isentrope control.
