The fundamental algorithm of light beam propagation in high power laser system is investigated and the corresponding computational codes are given. It is shown that the number of modulation ring due to the diffraction is related to the size of the pinhole in spatial filter (in terms of the times of diffraction limitation, i. e. TDL) and the Fresnel number of the laser system; for the complex laser system with multi-spatial filters and free space, the system can be investigated by the reciprocal rule of operators. 相似文献

1964年10月,王淦昌在他开创性的论文中指出:“目前国内外,都在研究和制造可以产生大能量和大功率的光激射器(即莱塞)。我们认为若能使这种光激射器与原子核物理结合起来;发展前途必相当大;其中比较简单易行的就是使光激射与含氘的物质发生作用,使之产生中子。”他在这篇论文里,对利用高功率激光照射含氘物质产生中子的原理、高 相似文献
