In this article, the activities to fabricate the polystyrene micro-shells by the microencapsulation method for laser fusion targets are presented. To reduce the Rayleigh-Taylor hydrodynamic instabilities in the process of target compression, the target requires a spherical symmetry, excluding any impurity with pre-defined elemental distribution. The polystyrene shells have wall thickness 27±2 µm and diameter 750±50µm, respectively. The transmission holographic Mach-Zehnder interferometer method has been utilized to characterize the micro-shell quality by measurement of the wall thickness and nonuniformity of the micro-shells.

This paper deals with the role of fast ignitor in fast-shock ignition (FSI) concept. The semi-analytical model indicates that the FSI target gain is a function of fast ignitor laser wavelength. If the energy of fast ignitor driver is and the laser wavelength is less than 0. 53 micron، then with a fuel mass about 2 mg the FSI has a considerable advantage over pure shock ignition and the figure of merit is better than 1. 2. When the wavelength of fast ignitor becomes shorter، the approaches، and for wavelengths shorter than 0. 25 micron no additional is advantage is obtained.
