华盛顿讯——据国防部和国会官员们说,劳伦斯——利弗莫尔实验室在高能激光器技术方面有了突破,有可能挫败苏联核武器对美国的攻击。 在内华达地下核试验场地进行的最近一次试验中,这个实验室论证试验了——在一个模拟空间环境的真空室中——一个非常小的、结构紧凑的,用一个小型核爆炸装置产生的X射线泵浦的激光器。 激光器在X射线（波长0.0014微米）波段工作,并且它能产生一个强度非常高的脉冲光 WASHINGTON - Lawrence and Congressional officials said a breakthrough at high-energy laser technology by the Lawrence-Livermore Laboratory could thwart Soviet attacks on the United States. In a recent experiment at the underground nuclear test site in Nevada, the laboratory demonstrated that - in a vacuum chamber simulating a space environment - a very small, compact X-ray generated by a small nuclear explosive device Ray-pumped laser. The laser operates on X-ray (wavelength 0.0014 microns) band and it produces a pulsed light of very high intensity
