Experiments on laser-induced thermonuclear fusion require high brightness lasers capable of producing subnanosecond pulses with total energy content of several kilojoules. Of existing laser media, Nd:glass appears to be the best choice for meeting these criteria. In this paper we discuss the problems of designing a high power Nd:glass laser system. A detailed description of an operating two-beam system producing subnanosecond pulses with a maximum energy of 350 J per beam is presented, along with an extensive description of beam diagnostic techniques. A four beam version of this system became operational on 3 April 1974 and is now producing energies in excess of a kilojoule in subnanosecond pulses.
激光诱导热核聚变实验需要高亮度激光器，这种激光器要能够产生总能量为几千焦耳的亚纳秒脉冲。在现有的激光介质中，钕玻璃似乎是满足这些标准的最佳选择。在本文中，我们讨论了设计高功率钕玻璃激光系统的问题。文中详细描述了一个正在运行的双光束系统，该系统能产生亚纳秒脉冲，每束光的最大能量为350焦耳，同时还广泛介绍了光束诊断技术。该系统的四光束版本于1974年4月3日投入使用，目前能在亚纳秒脉冲中产生超过一千焦耳的能量。
