    We present the experimental results of hyperpolarized 129Xe spectral line amplitude obtained by 4.7 T NMR system and high power semiconductor laser with reduced emission linewidth. The hyperpolarization process was based on the spin exchange collision technique between 129Xe atoms and optically pumped Rb atoms. The amplification of the 129Xe spectral line amplitude about 400 times was achieved. Furthermore, the influence of the optical pumping duration to the 129Xe spectral line amplitude was surveyed.
