[ 1 ] - تحلیل طیفی رفتار بازتابنده مزدوج فازی برای تقویت‌کننده اپتیکی دوعبوری

In this paper, the spectral behavior of a two-cell phase conjugated mirror (PCM)with a two-pass Nd:YAG amplifier has been analyzed experimentally and theoretically. For this purpose, amplifier input intensity for the three different states of laser oscillator with one, two and three longitudinal modes have been investigated. The numerical model is based on 2-dimension equations of stokes back-s...

[ 2 ] - نقش محرک سریع در روش افروزش سریع- شوکی

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 o...
